摘要
针对北运河杨洼船闸渗透变形破坏、地震液化、地下水控制及天然建筑材料平衡、水环境亲水安全等问题,采用综合地质测绘、综合工程物探、地质钻探、原位测试、水文地质试验、室内试验、水环境质量调查、BIM等技术对建设场地进行勘察,并对主要工程地质问题进行深入研究。结果表明,采用标准贯入和静力触探综合确定了场地地震液化下限,原状砂土的室内试验确定基础持力层的物理力学性质及其渗透变形等参数;现场抽水试验提出船闸基坑地下水控制的水文地质参数;BIM对开挖弃土工程量进行精细计算;水质的全分析确定水体对人体不会造成健康风险,勘察效果良好。
In view of the problems including seepage deformation,seismic liquefaction,groundwater control,natural building material balance,and hydrophilic safety in the water environment of Yangwa ship lock of China's North Canal,this paper uses comprehensive geological mapping,comprehensive engineering geophysical prospecting,geological drilling,in-situ test,hydrogeological test,laboratory test,water environment quality survey,BIM,and other technologies to investigate the construction site and conducts in-depth research on main engineering geological problems.The results show that the standard penetration and static cone penetration determine the lower limit of seismic liquefaction in the site,and the laboratory test of undisturbed sand obtains the physical and mechanical properties and seepage deformation parameters of the foundation bearing stratum.The field pumping test reveals hydrogeological parameters of groundwater control in the ship lock foundation pit.BIM finely calculates the amount of excavated spoil.The comprehensive analysis of water quality confirms that the water will pose no health risks to humans,and the investigation yields favorable results.
