Abstract

The invention provides a correction method for the foundation bearing capacity characteristic value. The correction method comprises the steps that (1) a flat plate loading test is carried out; (2) aload settlement curve is drawn; (3) the foundation characteristic bearing capacity is determined according to the types of the load settlement curve; (4) the different types of the foundation bearingcapacity are corrected by adopting corresponding correction formulas; and (5) the accurate foundation bearing capacity characteristic value is obtained. According to the correction method, by utilizing the characteristic bearing capacity correction formulas, the foundation bearing capacity obtained under the different foundation conditions and through the loading test of flat plates with the different specifications is corrected, the result of the flat plate loading test is more precise, more standard and more unified, and the reliable data basis is provided for basic design of a building foundation.

Description

technical field [0001] The invention relates to the technical field of in-situ measurement of foundation bearing capacity, in particular to a method for correcting characteristic values ​​of foundation bearing capacity. Background technique [0002] The plate load test is to keep the natural state of the foundation soil, apply static loads to the foundation soil step by step on a certain area of ​​the bearing plate, observe the foundation settlement under the loads of each level, and draw the load-settlement curve according to the test results. An in situ testing method for determining the bearing capacity of foundations and their deformation characteristics. The plate load test is equivalent to simulating the working conditions of the building foundation in the test, so it has the advantages of directness, intuition and reliable data. It is currently the most important method for determining the bearing capacity of the foundation and its deformation characteristics in vario...
