位于天津滨海软土地基土某工程场区地质条件较复杂,工程对地基的要求较高。在勘探工作中,对拟选厂址以标准贯入(S.P.T),室内土工试验为主要手段,做了方格网式的普遍勘探,对中心控制孔作了重型动力触探,静力触探,十字板剪切等原位测试。其中动力触探与标贯孔深达80米,静力触探与十字板剪切试验达18—20米。还进行了必要的工程地质及水文地质工作。现侧重对在本次勘察中应用原位测试方法的情况进行探讨,以供参考。
The geological conditions of a project site in Tianjin Binhai soft soil foundation are relatively complex, and the requirements for the foundation of the project are relatively high. In the exploration work, SPT was selected for the site to be selected, indoor soil tests were the main means, a general grid-type survey was performed, and heavy-duty dynamic probing, static probing into the central control hole was performed. Cross plate shear and other in-situ tests. Among them, the dynamic penetration and the standard penetration hole are as deep as 80 meters, and the static penetration test and the cross plate shear test are 18-20 meters. The necessary engineering geology and hydrogeological work were also carried out. It is now focused on the application of in-situ testing methods in this survey for reference.
