Abstract

This invention relates to a new type of experiment apparatus in pile-soil operation chamber, which is to mock up and test the interaction of pile-soil under multiple conditions in the chamber. It comprises upper cap-mud pressure load apparatus, barrel and balance load system, wherein, several set wires go through the side wall, bottom of barrel and pressure load cap to exert double pressure on the imbedded model peg, meanwhile to measure the pile-soil interaction under the alternating load. This invention can be applied to study the foundation bearing principle and to test various bearing abilities.

Description

Technical field:

[0001] The invention develops an indoor test device suitable for pile-soil action test, which is mainly used in foundation bearing mechanism research and various foundation bearing capacity tests. technical background:

[0002] At present, indoor geotechnical tests are mainly carried out on soil samples. The force is applied by pushing force. The samples are small. Only the physical and mechanical indicators of the soil are tested, and the pile-soil interaction cannot be fully tested. On-site tests include methods such as testing the bearing capacity of pile foundations, as well as relatively mature technical procedures, but the cost is high, and usually it can only be carried out in conjunction with engineering, and the test conditions are difficult to accurately control or repeat.

[0003] In various engineering design and construction, foundation bearing capacity is the key factor of project quality and construction cost. The development of new foundation...
