Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an impact analysis device, and more particularly to an impact analysis device for analyzing the influence of the civil engineering work on the surroundings before the civil engineering work or the like is performed.

[0002]

2. Description of the Related Art When civil works such as road works, water works, and construction works for buildings are performed, there is a possibility that vibrations and ground subsidence caused during the work may cause damage to surrounding buildings, such as cracks and inclinations. is there. Conventionally, in order to compensate for this damage, workers have to investigate the damage situation of the buildings around the construction site individually after the construction is completed, calculate the amount of damage based on the information obtained by the survey, and compensate It is carried out.

[0003]

As described above, the work involving excavation affects a wide area from the work site, and the amount of damage may be enormous. For this reason, it is necessary to predict the influence on the surroundings by an appropriate method at the time of design and construction planning, and to prevent damage from occurring.
At present, in large-scale construction, the amount of settlement of the surrounding ground is predicted using an analysis method of FEM (finite element method), and the influence range of the construction is actually calculated.

[0004] However, in order to predict the range of influence using the above-described analysis method, a high degree of specialized knowledge is required, and at present, a large amount of cost and days are required.
In a large-scale construction where excavation is several tens of meters, the range of influence of the construction is expected to be wide and the resulting damage is expected to be significantly large. In many cases, sufficient prediction has been considered. On the other hand, for small-scale construction with excavation of several meters, the person in charge of the construction lacks knowledge and recognition,
Just because of cost or simply because the drilling is shallow,
No consideration is given to predicting the range affected by the construction in advance. However, in many cases, the work that causes damage and causes problems is a small-scale work, and it is difficult to respond to unexpected damage that has occurred. Making progress difficult.

Conventionally, the above-mentioned small-scale construction has not been rationally studied depending on the construction contents, soil conditions, and the like. It is expected to be affected by the construction. This is based on the empirical rule that when excavation is performed, the earth mass in a range rising from the bottom of the excavation at 45 ° around the construction site becomes unstable. As described above, the irrational result that damage has occurred in places where investigations have not been carried out despite the fact that many unnecessary investigations have been carried out in the past, which is largely based on empirical rules, and that it is difficult to respond, has the unreasonable result. Inviting.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is simple, quick, and inexpensive at a reasonable cost without requiring specialized knowledge by a reasonable method. An object of the present invention is to provide an impact analysis device capable of performing analysis.

It is characterized by comprising analysis means for analyzing the range affected by the work for each layer, and display means for displaying the range affected by the work based on the analysis result analyzed for each layer.

Next, the principle of the analysis performed by the analyzer 22 of the present invention will be described. First, recently, the behavior of the ground has been analyzed using the FEM (finite element method) as a method for examining the effects of excavation. However, when the FEM is used, the ground data necessary for the analysis is accurately and accurately. Extensive research is required. In addition, the analysis requires a computer with a high processing speed, has a disadvantage that the cost is high and a long time is required until an analysis result is obtained. In the present embodiment, a method for simply and easily analyzing the range of influence is used. Hereinafter, an analysis method used in the present embodiment will be described.

FIGS. 3 and 4 are diagrams for explaining the principle of analysis performed by the influence analysis device according to one embodiment of the present invention. In these figures, an excavation work is taken as an example. 3 and 4 are vertical sectional views. FIG. 3 is a diagram for explaining the influence on the surroundings when excavation is performed when the soil quality of the soil is sandy soil.

As shown in FIG. 3, when the soil is sandy soil, the range affected by the ground surface is relatively limited. In FIG. 3, the range in which the influence occurs is a region denoted by reference numeral III, and this region is considered to be affected by ground displacement. In addition, the area denoted by reference numeral II is not directly affected by ground displacement, but is considered to be an area in which indirect effects will occur due to displacement of the soil mass in the area denoted by reference III. is there.

Here, the ground displacement when excavation work is performed will be considered. FIG. 4 is a diagram for explaining ground displacement due to excavation work. Although various ground displacements are conceivable due to the construction, the description here is simplified. FIG.
Reference numeral 72 denotes a ground surface before construction, and reference numeral 70 denotes a retaining wall when excavation work is performed. Assuming that the earth retaining wall is deformed as a curve denoted by reference numeral 74 in FIG. 4 by performing the excavation work, the ground surface 72 sinks and deforms as a curve denoted by reference numeral 76 in the figure. Here, the amount of deformation of the earth retaining wall deformation amount (code A _d are assigned in the drawing) and the ground surface (reference numeral A _s is in the figure
Are markedly equal.

The range indicated by the symbol L in FIG. 4 is a range in which the ground surface is affected by the construction, and the range indicated by the symbol I in FIG.
It corresponds to the part exposed on the ground surface in the range marked with I and III. still. Reference numeral 62 in FIG. 3 denotes a cutting beam that supports the retaining wall, and a curve denoted by reference numeral 64 indicates a deformed retaining wall due to construction. The symbol φ in FIG.
Is the internal friction angle of the soil, the code D ₂ is the depth occurring bends earth retaining wall. Also, the one with reference numeral 60 is
This is an existing building or the like, and this building 60 will be partially included in the area denoted by reference numeral II in FIG. 3, and thus may be affected during excavation work. Therefore, when considering the range that affects the construction, when the soil is sandy soil, the range of influence can be considered most rationally by considering the ranges indicated by reference numerals II and III.

Next, a case where the soil is clayey ground will be considered. FIG. 5 is a diagram for explaining the effect on the surroundings when excavation is performed when the soil quality of the soil is a viscous ground, and portions common to FIG. 3 are denoted by the same reference numerals. . In FIG. 5, the range affected by the construction is the range denoted by reference numeral III. Further, the range denoted by the reference symbol I is a range that is considered to have no effect.

The range believed to be affected, first, central angle 45 ° from the point resulting deflection of earth retaining walls around the uppermost point of the earth retaining wall (at a depth of D ₂₎ to the well-bore outward
Is drawn (an arc denoted by reference numeral 66 in the figure), and a tangent to the arc 66 is drawn from the end of the arc 66 (point denoted by reference numeral 68). As can be seen from FIGS. 3 and 5, when the soil is sandy soil, the influence of the construction does not spread relatively to the ground surface, whereas when the soil is cohesive soil, the influence range is the ground direction. You can see that it spreads to

FIG. 6 shows a case where the soil is composed of a plurality of layers.
It is a figure for explaining the analysis method of the influence range of construction.
In the example shown in FIG. 6, the soil is sandy, cohesive,
And sandy soil. Now, consider the case of analyzing the range of influence when excavating up to the third layer of sandy soil from the top.

In this case, the lowest point at which the influence occurs (the point indicated by reference numeral 72 in the figure) is set as a starting point, and as shown in FIG. 3, the internal friction angle φ of the soil is taken into consideration. Calculate the affected area when the soil is sandy soil. In this case, 45 ° + φ / 2 with respect to the horizontal direction from the point denoted by reference numeral 72.
Is drawn, and the position of the intersection (point denoted by reference numeral 74 in the figure) of this straight line and the boundary between the sandy soil and the cohesive soil is determined.

Next, when obtaining the influence range of the cohesive soil, an arc having a central angle of 45 ° is drawn from the point denoted by reference numeral 74 to terminate the arc (reference numeral 76 in FIG. 6). ) And a tangent to this arc is drawn from the end of the arc (the point denoted by reference numeral 76). And this straight line,
The position of the intersection (the point indicated by reference numeral 78 in the figure) of the boundary between the cohesive soil and the sandy soil as the upper layer is obtained.

Next, since the upper layer of the cohesive soil is sandy soil, the point denoted by reference numeral 78 is a starting point, and as shown in FIG. Ask for. In this case, a straight line having an angle of 45 ° + φ / 2 with respect to the horizontal direction is drawn from the point denoted by reference numeral 78, and the intersection between the straight line and the boundary of the ground surface (in FIG. Find the position of the attached point).

The range from the point with the reference numeral 80 obtained as described above to the retaining wall is the affected range L. that's all,

The example shown in FIG. 10 is an analysis result in the case of a relatively simple soil. In this case, the processing performed by the analysis unit 22 is only an extremely simple processing. In this example, the analysis unit 22 performs the process of obtaining the angle φ according to the input internal friction angle and the process described with reference to FIG. In FIG. 9, the processing becomes more complicated as the number of input layers increases. When the shield and propulsion method shown in FIG. 7 is analyzed, the analysis is performed using the equations (1) to (3).
