Background technique

The plate load test is the earliest and most widely used in-situ test method. The test is to apply loads in stages on a rigid bearing plate of a certain size, and observe the in-situ behavior of natural foundation soil with pressure and deformation under various loads. It can be used to: determine the bearing capacity of the foundation force according to the load-settlement relationship line; design the deformation modulus of the soil; estimate the undrained shear strength of the soil and the ultimate fill height. The plate load test is suitable for shallow foundations on the ground, especially for various types of fill and gravel-containing soils. Because the test is relatively intuitive and simple, it has been widely used for many years.

The flat plate load test generally uses a certain size of the bearing plate to be placed on the foundation soil to be tested. If it is a composite foundation test, it is generally necessary to lay a certain thickness of mattress under the bearing plate; Jack, a load platform is set up on the jack, and counterweights are stacked on the platform. Cement blocks and pockets of sand and gravel can be used as counterweights, and then the jacks are loaded step by step and the corresponding settlement is measured until the settlement of the foundation soil meets the unstable conditions. The bearing capacity of the foundation can be calculated by dividing the measured load weight by the area of the bearing plate.

The above-mentioned existing technical solutions have the following defects: as the working environment is different, the test foundation is different, and the size of the pressure-bearing plate that the staff needs to use is also different; the existing practice is usually based on specific situations, re-made A pressure-bearing plate; although this method can meet the different needs of users, it causes a great waste of resources.
