Research on Soil Parameters Based on In-situ Testing
This study systematically studied the mechanical parameters of in-situ soil in a certain foundation pit project with changes in soil moisture content and compaction degree through indoor tests and borehole penetration tests on backfill soil samples.The research results of this article indicate that,with changes in moisture content and compaction degree,the unconfined compressive strength,cohesion,and internal friction angle of soil exhibit specific trends.The trend of drilling parameters is basically consistent with the trend of unconfined compressive strength and cohesion of soil.A relationship model between torque,drilling pressure,and soil parameters was established through multiple linear regression analysis,And the reliability and accuracy of the model were verified in actual field testing.This study provides a practical testing and analysis method for the mechanical parameters of backfill soil.
