摘要
以典型复杂地层勘察项目为例,系统分析了复杂地层岩土勘察土工试验精度的影响因素,包括地层复杂性因素、设备与操作因素、环境与管理因素,并从采样环节控制、设备与流程控制两方面着手,提出复杂地层岩土勘察土工试验精度控制措施。工程实践表明,应用相关控制措施后,显著提高了勘察数据的可靠性,为深部地下工程设计提供了参考与借鉴。
Taking a investigation project in typical complex strata as an example,this paper systematically analyzes the influencing factors of geotechnical test precision during geotechnical investigation in complex strata,including stratigraphic complexity factor,equipment and operation factor,environment and management factor,and puts forward control measures for geotechnical test precision of geotechnical investigation in complex strata from two aspects of sampling link control,equipment and process control.The engineering practice shows that implementing relevant control measures significantly enhances the reliability of investigation data,providing reference for deep underground engineering design.
