摘要
软土地层中盾构法施工的盾构出洞段土体需要选择合适的加固技术进行处理,以满足施工稳定性的要求。采用三维数值计算方法,分别对冻结法、搅拌桩、搅拌桩+SMW工法加固条件下出洞段的加固土体进行分析,并对地层位移和应力进行比较,为施工时地层加固方法的选择提供理论依据。
In soft ground the soil of shield starting shaft should be improved by means of selecting method of ground improvement to meet the need of soil stability.Through 3-D numerical analysis,the ground movement and stress under each method of ground improvement (freeing method,stirring pile,stirring pile and SMW method) are analyzed and compared.The results will provide the basis for selecting methods of ground improvement.
