Apparatus for Model Footing and Underpinning Tests

摘要

An apparatus has been designed to study the underpinning and upgrading offootings by a pile at the center. In the paper, each piece of apparatus for the footing and underpinning tests is described in detail, including the test vessel, cylindrical membrane system, model pile and footing, drainage and back pressure system, pile jacking and loading system, the instrumentation and data logging, and leakage tests. The results of the one-dimensional consolidation stage of tests, model footing tests, and underpinning and upgrading by piles will be published in the future papers.
