摘要
以广州地铁九号线田美断裂带专项勘察为例,探讨了物探技术在查明断裂带的位置及特征、查清断裂构造与隧道的空间位置、研究断裂带的岩性和水文地质特征、预测隧道在断裂带中开挖所遇到的工程问题、提出工程措施建议等方面的优越性,为工程设计和施工提供地质依据。
Taking the special physical exploration of Tianmei fault for Guangzhou metro line nine for an example,the superiority characteristics of physical exploration have been discussed.These superiority features are embodied on many aspects,such as finding out the position and characteristics of the fault;investigating the spatial position between fault structural and tunnel;studying the rock character and hydrogeological characteristics of the fault;prediction the engineering problems which may encounter during the excavation in fault and putting forward the suggestion of engineering measures.This technology can provide geology foundation for the engineering design and construction.
