地铁对地质的影响1（The influence of subway on geology 1） Guangzhou - the geological condition is very complicated, but the subway construction has worked out a set of mature experience. (data, pictures) Guangzhou Metro Corporation Vice President of an exclusive interview with this newspaper, self created shield law to solve geological problems Thematic co-ordinate new express reporter Zhang Yingzi Special executive new express reporter Xu Jing Guangzhous geology is so complex, how will it affect the subway network being built on a large scale? The safety of subway construction and operation is not safe? In this regard, said deputy general manager of Guangzhou Metro Company Chen Shaozhang an interview with this newspaper: Guangzhou is not suitable for the construction of the subway in Guangzhou in 1962 that long-standing, the first geological exploration report on this conclusion, not suitable for the construction of Metro Guangzhou geology.

History Geological problems delayed the birth of the subway Chen told reporters, from the Guangzhou urban rail transit network planning process, in 1962, Guangzhou will have the first geological survey report. It has been pointed out in the report that the geological conditions in Guangzhou are characterized by the undulating topography and the complex lithology and diversity of the strata. The three major geological problems in Guangzhou are: one is the development of a number of Guangzhou subway line after the fault rifted, Guangcong fault, Shougouling fault more than 10. The biggest problem is the fracture zone surrounding rock crushing, relatively complete rock belongs to the weak interlayer, accidents caused by water inrush, engineering easily in tunnel construction; two is granite, mixed granite eluvial multi. When soaked in water, the soil will quickly soften and disintegrate and flow, c
