[0002] Pile foundation static load test is a technology for detecting the bearing capacity of pile foundation in engineering. In determining the ultimate bearing capacity of single pile, it is the most accurate and reliable test method. As a basis for determining whether a dynamic load test method is mature, the comparison error of static load test results is used. Therefore, each foundation design specification lists single pile static load test as the first priority. With the research of various prediction theories, some scholars in China have proposed the gray prediction theory to estimate the ultimate bearing capacity. Gray prediction theory is a new theory developed in the past twenty years. It has been widely used in industry, agriculture, energy, transportation, social science and many other fields. Many people have applied this theory to geotechnical engineering and achieved obvious results. Using this method, the corresponding pile load values at different settlements can be predicted through part of the known data of the load test.

[0003] The patent specification with publication number CN2261449Y discloses a pile foundation static load test frame composed of pile foundation, anchor pile and horizontal pressure rod. Its feature is that the static load test frame adopts a symmetrical three-link structure, with the main stand as the center. The main stand and each tension rod and horizontal pressure rod form several symmetrical triangular support frames. The tension points of the test frame are connected with the anchor pile reinforcement by screw mechanism, which can adjust the distance between the entire test frame and the anchor pile. The connection between the tension points of the test frame and the anchor pile reinforcement adopts a clamping form. The utility model can apply a load of up to 3300 tons to the pile foundation. The test frame is in force balance, safe to operate, suitable for various site conditions, and easy to install and disassemble.
