摘要
非开挖技术逐渐成为城市管网建设的主要技术,其常用的方法以顶管法和定向钻法为主,但实施这些技术需要比较全面地预知施工区域内的地下信息才能确保工程顺利进行。地球物理探测主要用于探测岩层信息,发现地质问题,方法较多,理论涵盖物理学的各个学科,比较适用于非开挖工程的前期勘查。西气东输上海管网建设对地球物理探测技术进行了大量应用,发现它确实有很突出的应用价值,值得积极推广。
The trenchless technology gradually become the main technology of city pipe network construction, its commonly used method include jack method and directional drill method, but to implement these technical require a comprehensive detailed knowing about the underground information in the construction region in advance, that can guarantee the project smoothly to carry on. The geophysical survey is mainly used in surveying the rock layer information, to discovery the geological question, the method are more, the theory covers the physics each discipline, which is suitable for the earlier period investigation of trenchless project. The West -East natural gas transmission Shanghai pipeline networks construction has carried on the massive applications of the geophysical survey technology, discovered it truly has the very prominent application value, and is worth positively promoting.
