岩土工程勘察室内试验误差分析及解决对策

Error Analysis and Countermeasures of Laboratory Test in Geotechnical Engineering Investigation

室内土工试验是岩土工程勘察的核心工作之一,试验结果直接决定着工程的安全、质量与经济条件。为提供真实、可靠、准确的土工试验报告,必须从现场取样、土样运输、保管、室内土工试验、数据处理、报告审核等全过程进行严格管控。该文针对室内土工试验的客观误差和主观误差进行了全面系统的分析,主要从土工试验阶段和数据处理阶段两方面进行了分析和探讨,并提出了相应的解决对策,具有一定的指导和借鉴意义。

Laboratory test is one of the core work of geotechnical investigation,and the test results directly determine the safety,quality and economic conditions of the project.In order to provide a true,reliable and accurate geotechnical test report,it must be strictly controlled from the whole process of on-site sampling,soil sample transportation,storage,indoor geotechnical test,data processing,report review,etc.This paper makes a comprehensive and systematic analysis of the objective and subjective errors of the indoor soil test,mainly from two aspects of geotechnical test stage and data processing stage,and puts forward corresponding countermeasures,which have certain guidance and reference significance for colleagues.
