磁梯度法在城市轨道交通工程建筑物基础调查中的应用
|
摘要
地铁工程建设前期均须对设计线路沿线周边环境进行调查,主要包括地下管线和建筑物基础调查。调查成果的准确性直接影响到地铁线路的设计和施工。建筑的基础资料仍是以收集资料为主,当遇到年代已久的建筑或城乡结合部的村民自建房等,则常出现收集不到既有的基础资料。在此情况下,为保障地铁工程设计、施工的顺利实施,就需采用物探等其他手段来获取建物桩基础等资料。磁梯度法在广州十八号线工程中,探测既有建筑物桩基长度取得了较好的效果。
In the early stage of subway project construction,the surrounding environment along the design line must be investigated,mainly including investigation of underground pipelines and buildings.The accuracy of survey results directly affect the design and construction of subway lines.The basic information of the architecture is still based on the collected data.When the villagers have built their own houses in the long history of building or urban-rural fringe,they often fail to collect the existing basic data.Under this circumstance,in order to ensure the smooth implementation of subway engineering design and construction,other means such as geophysical exploration are required to obtain information such as the foundation of building materials.This paper introduces the application of magnetic gradient method in the detection of the length of existing building piles in Guangzhou No.18 line project,and achieves good results.
