Problems solved by technology

However, there are still some shortcomings: the boundary conditions of the pile foundation, the mechanical properties of the soil layer and other factors are not easy to control; when using the prototype material to make the model, it can reflect the pile-soil interaction, force characteristics and deformation characteristics of the pile foundation. It i

Abstract

The invention relates to a multifunctional pile foundation model testing system and an assembling and testing method thereof. The multifunctional pile foundation model testing system comprises a base, guide rails, a model frame, a loading system, a measuring system, a collecting device and a prefabricated pile body. The loading system comprises a loading device and a reaction frame and can achieve automatic control and set the load and the loading time autonomously. The measuring system is composed of different kinds of measuring equipment including an earth pressure cell, a sensor and a strain gauge. The collecting device can achieve automatic collecting and is connected with a digital display system. The digital display system comprises software which can provide data tables and has an automatic curve drawing function. The testing system is easy to operate, rich in function and capable of researching bearing characteristics of single piles and pile groups under different conditions, in different bearing stratums and of different types. Obtained results are more accurate, settlement data can be effectively measured, the process that the bearing characteristics of a pile foundation are achieved can be successfully simulated in the actual process, and effective reference bases are provided for guidance of pile foundation design and pile foundation bearing characteristic theory research.

Description

technical field [0001] The invention relates to a multifunctional pile foundation model test system and its assembly and test methods. Background technique [0002] The function of the pile foundation is to transmit the upper load to the lower hard rock formation. Because of its excellent characteristics of high bearing capacity and small settlement, the pile foundation is more and more widely used in urban high-rise buildings, port terminals and earthquake-resistant projects. . Therefore, it is of great significance to further study the bearing capacity characteristics of pile foundations through experiments. [0003] The static load test of the prototype pile on the engineering site is the most direct and reliable method to design and determine the bearing capacity of the pile foundation and study the bearing deformation performance of the pile foundation. However, due to the long test period, high cost, complex boundary conditions, many influencing factors and easy Limi...
