摘要
以浙江某地电缆改迁工程为背景,针对软土地基中电缆沟产生不均匀沉降的问题,提出了换填法和水泥搅拌桩法的地基处理方案,并采用有限元法对处理方案进行了建模分析,认为在软土地层中根据地层分布情况酌情采用换填法或水泥搅拌桩法能够有效控制电缆沟工后沉降,最后,现场监测的工后一年沉降数据,进一步验证了该处理方案的有效性。
Taking a cable diversion engineering in Zhejiang as the background,according to the uneven settlement problems of cable trench in soft soil foundation,put forward the ground treatment scheme of replacement method and cement mixing pile,and using the finite element method made modeling analysis on treatment scheme,in soft soil foundation,according to the strata distribution situation discretion using the replacement method or cement mixing pile method could effectively control the cable trench settlement after construction,finally,the one year settlement data after construction of on-site monitoring,further verified the effectiveness of the treatment scheme.
