重大工程中的断裂构造探测

Fracture structure detection in major project

工程建设中的断裂构造对场地稳定和建筑物安全的影响已经引起了重视,针对断裂构造成因复杂、大小不一、埋藏深度不一、内含物的成分及性状差异极大,造成对断裂构造探测的针对性、直观性不足的问题,进行探测技术路线和探测方法的研究和论述,采用基于区域地质条件分析,运用多种手段对表部和隐伏的断裂构造进行深入的探测方法,探测成果直观、可靠,对工程建设宏观的安全性评价、研究场地内断裂构造对工程的影响提供详尽的资料。结合上海洋山深水港区LNG码头和后方堆场工程,验证该探测技术路线和方法能有针对性地、直观地探测工程场地内的断裂构造。

The fracture structure in the construction of the security and stability of site building has attracted attention.The cause of the fracture structure is complicated, different in size, different in depth, and the composition and character of the contents are very different.The fracture structure detection is lack of pertinence and intuition. Based on the analysis of regional geological conditions, we study the technical route and the method of detection, and use a variety of measures to detect the surface and the hidden of fracture structure. The detection results are intuitionistic and reliable, and can provide the detailed information of the macro safety evaluation of the engineering construction and the impact of the fracture structure on the engineering.Combined with the project of LNG wharf and rear yard engineering of the Yangshan Deepwater Port, the results are verified that the route and method of the detection technique can detect the fracture structure in the engineering site directly and pertinently.
