The Technology And Management Research On The Earth Pressure Balance Shield Through The High-speed Rail

Currently, the state has increased investment in urban rail transit, and thelimitation of the City land area ,the rail transport increasingly clear downward trend.In addition, the train speed rail transportation has become an important task ofdevelopment, and operation of high speed train railway track the impact of growing,and address the situation through the formation of more complex, prone to landsubsidence shield construction and deformation , the local table is too large settlementmay endanger the surrounding buildings and the safety of underground pipelines andother structures, if the shield of the existing railway tunnel through the technicalissues do not attach importance on people's lives and property and will bring seriousdamage to national interests. Therefore, the shield through the existing railwayconstruction technology is an important topic worthy of study.The paper introduce that the shield construction management system combinewith practice, By combining theory with practice research methods, Summarizes theConstruction method of the geological cross Tianjin Intercity Railway. The mainresearch contents include the following:(1)According to the characteristics of the engineering, Summary the organizationconstruction and management of the railroad crossing, Through the systemconstruction, Formed the efficient organization system.(2)Though analyzing the specific engineering ground settlement, and with a largenumber of actual data analysis, summary, then get the stratum settlement rule;(3) Using the information construction monitoring method, To guide the theparameter optimization, Soil improvement, water pressure control of constructionprocess. And summarizing the experience of though the high-speed rail project of theTianjin soil conditions, In order to provide a reference for similar engineering basis.
