根据临近场地地质灾害评估报告，本工程范围内基岩埋深大于 320m，岩性

According to geological disaster assessment report near the site, within the scope of this project bedrock depth greater than 320m, lithology is mainly Paleogene Paleocene summer driving bridge group reddish brown, dark red silty mudstone, mudstone and muddy siltstone containing quartz and fine gravel Paleogene Paleocene Northbridge group reddish brown, gray-brown mudstone, silty mudstone, sandstone and basalt folder fine powder; Shanghai area tectonic units belonging to the Yangtze paraplatform western Zhejiang - West Anhui platform fold belt and under North East extension of the Yangtze platform fold belt, the geological history to uplift the overall performance of the state, in order to break the main tectonic activity, combined with a slow down, to fracture obtained by dividing the forward fault block uplift. According to the existing bedrock geology survey results: The main speculation surrounding the proposed distribution of faults field areas Ma - Jinhui break. Most of these faults deep crust to generate an earlier era, but do not belong to the Quaternary active faults and modern, the earthquake rupture, and thus no impact on the project.

根据临近场地地质灾害评估报告，本工程范围内基岩埋深大于 320m，岩性主要为古近系古新统夏驾桥组棕红、暗红色粉砂质泥岩、泥岩和泥质粉砂岩含石英细砾及古近系古新统北桥组棕红、灰褐色泥岩、粉砂质泥岩、夹粉细砂岩和玄武岩；上海地区大地构造单元属于扬子准地台浙西—皖西台褶带和下扬子台褶带的北东延伸部分，在地质历史时期总体表现为隆起状态，构造活动以断裂为主，辅之缓慢升降，为断裂分割而成的正向隆起断块。根据已有基岩地质调查成果：拟建场地区周围分布的主要推测断裂构造有马桥-金汇断裂。这些断裂大多深切地壳、生成年代较早，但均不属于第四纪活动断裂和现代中、强震断裂，因而对本工程建设无影响。

According to the geological hazard assessment report of the adjacent site, the buried depth of the bedrock within the scope of the project is greater than 320m, mainly composed of brown red, dark red silty mudstone, mudstone and argillaceous siltstone of Paleogene Paleocene xiajiaqiao formation with quartz fine gravel, and brown red, gray brown mudstone, silty mudstone, mixed with siltstone and basalt of Paleogene Paleocene Beiqiao formation; the geotectonic unit of Shanghai area belongs to the north-east extension of the West Zhejiang Wanxi platform fold belt and the lower Yangtze platform fold belt of Yangtze paraplatform In the geological history, it is generally in the uplift state, and the tectonic activity is mainly fault, supplemented by slow rise and fall, which is a positive uplift fault block divided by fault. According to the existing bedrock geological survey results, the main presumed fault structure around the proposed site area is Maqiao Jinhui fault. Most of these faults are deep-seated in the earth's crust and formed early, but they are not Quaternary active faults and modern medium and strong earthquake faults, so they have no impact on the construction of the project.<br>
