Description

  In the present invention, the stress level of the model ground is simulated using the centrifugal force, the load is applied to the model ground with a static loading device, and the displacement of the model ground is measured. The present invention relates to a static loading method of a centrifugal model experiment for predicting behavior and a static loading device used for the centrifugal model experiment.

  In order to grasp the actual behavior of the building (the behavior of the actual ground), it is certain to investigate the behavior using the real thing. However, when an experiment is performed using an actual object, it is necessary to construct (manufacture) a large-scale model, which requires a great deal of labor and cost.

  On the other hand, the stress level of the model ground is made to simulate the actual ground using centrifugal force, and the relationship between the stress and strain (displacement) is reproduced in the same way as the actual ground. A centrifuge model experiment that can more accurately grasp the behavior of the real object has attracted attention (for example, see Patent Document 1).

For example, when a subsidence experiment is performed in this centrifugal model experiment, as shown in FIGS. 7 and 8, the sample ground 1 is filled with the model ground G, and the displacement meter 2 and the ground pressure meter 3 are arranged at predetermined positions. Then, a static loading device 4 for loading a load on the loading surface G1 (ground surface) of the model ground G is installed. Then, the sample container 1 (model ground G) is mounted on the centrifugal model experimental device together with the static loading device 4, and the stress level of the model ground G is measured using the centrifugal force by rotating at a predetermined centrifugal acceleration. Simulate the state. From this stage, a load is loaded on the loading surface G1 of the model ground G by the static loading device 4, and the vertical displacement (subsidence amount) and ground pressure of the model ground G are measured. For example, it is possible to predict the behavior of the actual ground at each stage of the building construction process by increasing the load stepwise according to the load that gradually increases in the actual building construction process and measuring the displacement against the load and the ground pressure. It becomes possible.

For this reason, in the actual building construction process, the load distribution of the building is constant, and the vertical displacement of the actual ground is often distributed according to the load and underground stress, whereas the loading surface where the displacement distribution occurred Since an equally distributed load cannot be loaded on G1, there is a problem that the subsidence phenomenon of the actual ground where the vertical displacement is distributed according to the load and the underground stress cannot be faithfully reproduced.

  Hereinafter, a static loading method of a centrifugal model experiment and a static loading device used for the centrifugal model experiment according to an embodiment of the present invention will be described with reference to FIGS. In the present embodiment, the stress level of the model ground is simulated using the centrifugal force, the load is applied to the model ground with a static loading device, and the vertical displacement of the model ground is measured. The present invention relates to a static loading method of a centrifugal model experiment for predicting the behavior of an actual ground and a static loading device used for the centrifugal model experiment.

  First, in this embodiment, the centrifugal model experimental device is a well-known arm-movable centrifugal loading experimental device, which is fixed to a rotating shaft provided with a rotating shaft arranged in a vertical direction, and an upper portion of the rotating shaft.

Centrifugal force acts. Thereby, while reaching a predetermined centrifugal acceleration, the stress level of the model ground G becomes a state simulating the actual ground. Then, when the stress level of the model ground G is reproduced by simulating the actual ground, it is possible to predict the settlement behavior of the actual ground by loading the model ground G and measuring the displacement.

  Here, as shown in FIGS. 1 and 2, the static loading device 10 for loading a load on the model ground G includes a frame 11 provided integrally with the sample container 1, and the sample container 1. Liquid replenishment tank 12 attached to and supported by the upper portion of frame 11 located above, loading tank 13, and liquid connected to liquid replenishing tank 12 and loading tank 13 via electromagnetic valve 14a A supply pipe 14 and displacement meters 15, 16, and 17 are provided.

  The liquid replenishing tank 12 is a tank for storing a liquid (loading body having fluidity) W for loading a load on the loading surface G1 of the model ground G filled in the sample container 1, and this loading liquid W For example, water or heavy liquid such as SPT (sodium polytungstate) or liquid mercury is stored.

  As shown in FIGS. 1 and 2, the loading tank 13 is formed in, for example, a rectangular tube shape, and is supported by connecting the upper end side to the frame 11, and the opening 13 a on the lower end side is connected to the model ground G. It is arranged on the loading surface G1 (ground surface). As shown in FIG. 3, the loading tank 13 is a bag for storing the liquid W supplied from the liquid supply tank 12 by opening the electromagnetic valve 14 a of the liquid supply pipe 14 in the loading tank 13. A flexible film body 20 is provided. The film body 20 is opened at the upper end side of the loading tank 13, and the bottom portion 20 a is disposed on the opening 13 a side at the lower end of the loading tank 13, and is installed in a state of being loosely inserted into the loading tank 13. Yes. Further, the membrane body 20 is interposed between the liquid W supplied and stored from the liquid replenishment tank 12 and the loading surface G1 of the model ground G through the opening 13a of the loading tank 13, and centrifugal force Is always provided so that the bottom 20a of the film body 20 is in close contact with the loading surface G1 of the model ground G.

  The displacement meters 15, 16, and 17 are contact displacement meters. As shown in FIGS. 1 to 3, the displacement meter bodies 15a, 16a, and 17a are connected to the displacement meter bodies 15a, 16a, and 17a so as to be extendable and contractable. It comprises rods 15b, 16b, 17b and target plates 15c, 16c, 17c with which the tip portions of rods 15b, 16b, 17b abut. The displacement meter bodies 15a, 16a, 17a are attached to and supported by the upper part of the frame 11, and the rods 15b, 16b, 17b are arranged inside the film body 20 (loading tank 13). The rods 15b, 16b, 17b The target plates 15c, 16c, and 17c with which the tip ends of the film body 20 are attached are installed inside the bottom portion 20a of the film body 20. In the present embodiment, three displacement meters 15, 16, and 17 are installed so as to measure the center of the loading surface G1 of the model ground G and the displacements on both the left and right sides of the center. Since the displacement meters 15, 16, and 17 installed in this way are attached to the bottom 20a of the film body 20 that is in close contact with the loading surface G1 in a state where the centrifugal force is applied to the target plates 15c, 16c, and 17c. The target plates 15c, 16c, and 17c are displaced together with the loading surface G1 of the model ground G, and the displacement of the model ground G (loading surface G1) can be measured through the film body 20.

  Next, a method for loading the model ground G with the static loading device 10 having the above-described configuration and performing a settlement experiment in the centrifugal model experiment will be described, and the static loading method and the centrifugal model of the centrifugal model experiment of the present embodiment will be described. The operation and effect of the static loading device 10 used in the experiment will be described.

  When conducting a settlement experiment in the centrifugal model experiment, first, the sample container 1 and the frame 11 filled with the model ground G are mounted on the platform of the centrifugal model experimental device. Next, the loading tank 13 provided with the film body 20 is attached to and supported by the frame 11, and the opening 13a on the lower end side thereof is disposed on the loading surface G1 of the model ground G and installed. Further, the target plates 15c, 16c, and 17c are installed on the bottom 20a of the film body 20, the displacement meter bodies 15a, 16a, and 17a are attached to the upper portion of the frame 11, and the tips of the rods 15b, 16b, and 17b are attached to the target plate 15c. , 16c, 17c, and the displacement meters 15, 16, 17 are installed. Further, the loading liquid W is put in the liquid supply tank 12 and stored.

  And in the stage which installed the static loading apparatus 10 in this way, the rotating shaft of a centrifuge model experimental apparatus is rotated, and a rotating arm is rotated. As a result, the sample container 1 filled with the model ground G and the platform loaded with the static loading device 10 are swung up as the centrifugal acceleration increases, reach a predetermined centrifugal acceleration, and the model ground G in the sample container 1 The stress level simulates the actual ground.

  When the stress level of the model ground G is reproduced by simulating the actual ground, the electromagnetic valve 14a is opened, and a predetermined amount is supplied from the liquid supply tank 12 to the inside of the film body 20 (loading tank 13) through the liquid supply pipe 14. The liquid W is dropped. When the liquid W is supplied into the loading tank 13 in this way, the bottom 20a of the film body 20 is brought into close contact with the loading surface G1 of the model ground G by the liquid W to which centrifugal force is applied, and the amount of the liquid W is determined. The predetermined load is loaded on the loading surface G1 of the model ground G. Further, when displacement occurs on the loading surface G1 of the model ground G according to this load, the bottom 20a of the flexible film body 20 is maintained in close contact with the loading surface G1 of the model ground G. Displacement (deformation) is performed together with the loading surface G1, and the liquid W having fluidity flows (follows) according to the displacement of the loading surface G1. For this reason, even when displacement distribution occurs in the loading surface G1, the liquid W always loads, for example, an evenly distributed load corresponding to the load of the building constructed on the actual ground onto the loading surface G1. .

  Further, when the bottom portion 20a of the film body 20 is brought into close contact with the loading surface G1 and displaced together with the loading surface G1, the target plates 15c, 16c, and 17c attached to the bottom portion 20a of the film body 20 are driven by the displacement of the loading surface G1. To be displaced. Thereby, the displacement amount of the loading surface G1 (the displacement amount (sinking amount) of the model ground G) is measured by the displacement meters 15, 16, and 17. Furthermore, by opening and closing the electromagnetic valve 14a and supplying the liquid W into the loading tank 13 step by step, the load is increased stepwise according to the load that sequentially increases in the actual building construction process. Measure displacement (settlement) with respect to stage load. At this time, the liquid W that flows in accordance with the displacement of the loading surface G1 is loaded with an evenly distributed load corresponding to the load of the building on the loading surface G1 at all times. The results measured at 16 and 17 faithfully reproduce the subsidence phenomenon of the actual ground where the vertical displacement is distributed according to the load and the underground stress.

  Here, FIG. 5 shows the center of the loading surface G1 when the amount of the liquid W is increased stepwise as shown in FIG. 4 and the load loaded on the loading surface G1 of the model ground G is increased stepwise. The measurement results of the left and right displacements are shown. From this test result, it is possible to reproduce the situation where subsidence occurs while loading loads step by step, and by capturing the displacement distribution in the loading surface G1, the vertical displacement is distributed according to the load and underground stress. It was confirmed that the settlement phenomenon can be faithfully reproduced.

  Therefore, in the static loading method of the centrifugal model experiment of this embodiment and the static loading device 10 used for the centrifugal model experiment, a load is applied to the loading surface G1 of the model ground G by using the liquid W (loading body having fluidity). The liquid W flows according to the displacement of the loading surface G1 (followed by the displacement of the loading surface G1), and always loads an evenly distributed load according to the load of the building constructed on the actual ground. It becomes possible to load on the surface G1. Thereby, it becomes possible to faithfully reproduce the subsidence phenomenon of the actual ground in which the vertical displacement is distributed according to the load and the underground stress.

  Further, by providing the film body 20 in the loading tank 13, the liquid W supplied to the loading tank 13 can be stored in the loading tank 13 by the film body 20. Then, the film body 20 is deformed so as to be always in close contact with the loading surface G1 according to the displacement of the loading surface G1, and the liquid W flows along with the deformation of the film body 20, so that the building always constructed on the actual ground It becomes possible to load an evenly distributed load corresponding to the load on the loading surface G1.

  Furthermore, by providing a plurality of displacement gauges 15, 16, and 17 and measuring the displacement at a plurality of locations on the loading surface G1, the displacement distribution of the loading surface G1 can be grasped, and the ground surface of the actual ground at the time of loading is obtained. It becomes possible to accurately predict the settlement distribution of (loading surface G1).

  Further, by using a liquid W such as water or heavy liquid as the loading body, the loading body (liquid W) flows reliably according to the displacement of the loading surface G1, and is always built on the actual ground. It is possible to reliably load an evenly distributed load corresponding to the load on the loading surface G1. Furthermore, at this time, by using heavy liquid as the liquid W, it becomes possible to supply a small amount of heavy liquid to the loading tank 13 and load a desired load, compared with the case where water is used, for example. In addition, it is possible to conduct a subsidence experiment and to make the liquid replenishing tank 12 and the loading tank 13 small. In addition, when SPT is used as a heavy liquid, it is harmless, and therefore, it is possible to handle it more easily than when liquid mercury or the like is used, for example.

  As mentioned above, although one embodiment of the static loading method of the centrifugal model experiment and the static loading apparatus used for the centrifugal model experiment according to the present invention has been described, the present invention is not limited to the above-described one embodiment. Changes can be made as appropriate without departing from the spirit of the invention. For example, in the present embodiment, the description has been made on the assumption that the loaded body is the liquid W. However, the loaded body according to the present invention only needs to have fluidity, and for example, metal powder particles may be used. Good. Moreover, when using such a granular material as a loading body, while supplying and storing in the loading tank 13, it is made to contact the loading surface G1 of the model ground G directly through the opening part 13a of the loading tank 13. Thus, it is possible to load a load on the loading surface G1. For this reason, the film body 20 is not necessarily limited to being provided in the loading tank 13.

  Further, in the present embodiment, the loading tank 13 is supported by attaching the upper end side to the frame 11, but the loading tank 13 is mounted on the model ground G without being supported by the frame 11. It may be provided.

  Furthermore, in the present embodiment, the centrifugal model experiment device has been described as an arm movable centrifugal loading test device. However, the present invention is also applicable when a subsidence experiment is performed using a drum type centrifugal loading test device. Is possible.

  In the present embodiment, the displacement meters 15, 16, and 17 are contact displacement meters. However, if the displacement of the loading surface G1 of the model ground G can be measured, the displacement meters are limited to the contact displacement meters. There is no need.

  Furthermore, as shown in FIG. 6, for example, the rigidity of an actual structure such as a foundation slab of a building constructed on the actual ground is simulated between the loading surface G1 of the model ground G and the liquid W (loading body). A simulated board 21 may be installed. In this case, the simulated plate 21 can reflect the influence of deformation such as the foundation slab of the building, and the load due to the loading body can be loaded on the loading surface G1 of the model ground G. For this reason, it is possible to capture a displacement distribution that is closer to reality, and it is possible to predict the settlement distribution of the actual ground with higher accuracy.
