摘要
收集了杭州地铁1号线盾构隧道、武汉长江盾构隧道引起的地层变形实测数据,对双线盾构隧道施工引起的地表变形规律进行了研究.采用Peck公式对14组数据进行了拟合分析,并给出了杭州和武汉地区双线盾构隧道施工地层变形预测的相关参数.研究结果表明,经典的Peck公式在分析和预测单线及双线盾构隧道施工地表变形中仍然适用,修正后的Peck公式是经典公式的有效补充,对预测双线盾构隧道引起的地层沉降具有重要意义.
With the rapid development of urban construction,the shield tunneling is widely used in urban rail transit and municipal engineering. The measured data of shield tunnel in Hangzhou Metro Line 1 and Wuhan Changjiang River shield tunnel are collected and the surface deformation law due to double shield tunnel construction is analyzed. Fitting 14 sets of data by use of Peck formula,it is discovered Peck classic formula is still applicable to analyse and forecast surface deformation because of single and double shield tunnel construction. Some key parameters have been given in this paper. The research results can not only provide a reference for similar engineering design and construction,but also of great significance to enrich database of similar projects.
