Application of tangent modulus method in nonlinear settlement calculation of foundation

open access: yesIOP Conference Series: Earth and Environmental Science, 2020
Abstract Foundation settlement calculation has been a difficult and hot problem in geotechnical engineering study. The problems lies in the large differences between the geotechnical parameters of field and indoor test. The using of the tangent modulus method based on the field loading test to determine the calculation parameters can ...

Determination of bearing capacity of foundation by pressure plate load tests

open access: yesYantu gongcheng xuebao, 2023
The bearing capacity of a foundation should be determined by its strength and deformation under the actual foot. It can be determined directly by the pressure plate load tests, which can ensure the strength safety, but can not ensure the deformation ...
