Research on Detection Technology of Foundation Bearing Capacity under the Rainfall Condition
In order to comprehensively detect the bearing capacity of foundation under the rainfall condition,this paper summarizes the current developed and applied foundation detection technology,and combines the rainfall environmental factors to detect the foundation bearing capacity of a project with 24 h precipitation of 25.6 mm.In order to better detect the bearing capacity of foundation,it adopts the in-situ test method of static contact method,and uses three groups of detection data to do weighted average analysis on the same foundation soil layer.The difference of foundation bearing capacity before and after rainfall is analyzed,and the change of foundation bearing capacity of the project after rainfall is analyzed through field detection data.The detection results show that the static contact test method can be well applied to the detection of foundation bearing capacity under the rainfall condition;rainfall condition cause different degrees of damage to the bearing capacity of the foundation,the maximum damage of cohesive soil is 3.58%,and the damage of miscellaneous fill is 1.72%.
