The Key Technology And Management Of Construction Of Futian Station Of Guangzhou-shenzhen-Hongkong Passenger Dedicated Line

Currently the stations in China are constructed by open-cut method (only a fewadopt subsurface excavation mothod in the geological conditions allow). Thearrangement of Guangzhou-Shenzhen Hong Kong Dedicated-Passenger Railway ofFutian Station is below the Yitian Road which is the main road of Shenzhen citynorth-south direction, road transit network is developed, a number of line havealready been built, under construction and planning of urban rail transit subway linesand intercity passenger line runs through within the scope of engineering, which ledto its construction is difficult, large-scale, large projects.so the project is using opencut method, center island method and covered top-down excavation method toconstruct.First, this article analyzes the engineering environment and engineeringhydrogeology of Guangzhou Shenzhen Hong Kong Dedicated-Passenger Railway ofFutian Station. Its geological conditions is very complex, the formation of soil, silt,silt soil, silty clay and fine sand, medium sand and coarse sand, gravel, sand, coarsegravel soil, full~weakly weathered granite Bad geological distribution of artificialfilled soil, uneven soil, artificial filled soil slope greening area compared to the moreloosely, the field distribution of silt soil (clay), has a large void ratio, highcompressibility, low shear strength, thixotropy, rheological property and thecharacteristics of the inhomogeneity. At the same time because of the station islocated in the downtown, there are a lot of high-level and high-rise buildingstandings on the ground, distribution of underground pipeline is dense and complex.Therefore， on the basis of repeated proof， the project is divided into a lot of itemsand make sure the construction methods of branch sub-item project in the project,clarifying that Guangzhou Shenzhen Hong Kong Dedicated-Passenger Railway ofFutian Station is using open cut method, center island method and covered top-downexcavation method which are the key construction technologies. Second, this articleexpounds the general construction scheme of Futian Station, formulating theconstruction schedule to strengthen the construction and management, and then determine the reasonable construction programs and technical measures to provide aguarantee for safety construction and the construction of civilization. In addition, thisarticle also illustrates the reasonable construction processes, machine arrangements,main material supply and organizes plans, and focused measures in Constructionmanagements of open cut method, center island method and covered top-downexcavation method. To comprehensive monitor and measure the foundation pit ismaking sure the construction method of the station implement successful.
