摘要:
以西安地铁二号线某区间工程土压平衡盾构施工为背景,基于监测数据的统计结果,结合现场渣土改良试验,研究了土压平衡盾构穿越黄土地层及全断面砂层时地表变形的主要影响因素及其控制技术,并根据计算结果给出了土压平衡盾构穿越含砂土层过程中的土舱压力、出土量、注浆压力和注浆量等变形主要影响因素的经验值.结果表明,土压平衡盾构穿越含砂土层过程中,表现出了较强的不适应性,但经膨润土泥浆对渣土进行改良后,盾构开行顺利,施工进度较快.当土舱压力、出土量、注浆压力和注浆量分别控制在140~260kPa、54~56m3、210~300kPa和每环4m3时,土压平衡盾构表现出了较好的适应性.相关结论可为类似工程解决土压平衡盾构对穿越土层的不适应问题提供参考
Abstract:
Certain interval engineering by the EPB shield machine in Xi′an Metro Line 2is taken as example. Based on the statistical results of the monitoring data, and combined with the sediment improvement test, make a research is carried out about the main factors and control technology of the surface deformation with the EPB shield machine driven across the sand of loess and the full section soil. Meanwhile, according to the analysis of the field test results, the empirical value of the main influencing factors such as soil warehouses pressure, volume of excavated earth, grouting pressure and grouting quantity etc are given. The result showed that when the EPB shield went through the sand layer, it showed a strong inadaptability. But after the sediment improvement test by the bentonite clay, the driving speed of the shield improved quickly and the construction progress became relatively fast. When the value of soil warehouses pressure, volume of excavated earth, grouting pressure and grouting quantity are respectively controlled at 140~260 kPa,54~56 m3,210~300 kPa and 4 m3,the EPB shield machine showed a satisfactory performance. The conclusions serves as a reference for the problems of inadaptability as the EPB shield machine was driven across the stratum in similar projects.
