摘要

    摘要
  • 摘要: 以中国移动甘肃公司一深基坑工程为实例,沿基坑开挖上口线周围共布设20个监测点,在基坑开挖施工过程中,分别对20个监测点的水平位移和竖向位移进行了实时监测。根据监测结果,分别对土钉加预应力锚杆的复合土钉墙、土钉墙和排桩加预应力锚杆三种支护结构的变形特性进行了分析。监测及分析结果表明,该深基坑工程支护设计方案合理,效果良好,满足了设计和环境的要求,本工程取得的经验对兰州地区类似基坑工程具有指导意义。监测结果同时还表明,土钉加预应力锚杆的复合土钉墙、土钉墙及排桩加预应力锚杆三种基坑支护形式在兰州地区的适用性。
    Abstract: Taking the deep foundation pit of China Mobile Group Gansu Co., Ltd. as an example, a total of 20 monitoring points are arranged around the excavation sideline of the foundation pit. The horizontal displacements and vertical displacements at the monitoring points are monitored respectively in real time during the process of excavation construction. According to the monitoring results, the deformation characteristics of soil-nailing composite pre-stressed anchor supporting wall, soil-nailing wall and row-pile composite pre-stressed anchor supporting structures are analyzed. The monitoring and analysis results show that the design scheme for the supporting structures is reasonable, the effectiveness is good and the requirements of design and environment are satisfied. The experience gained from this project plays a guiding role in the similar projects in Lanzhou. The monitoring results also show the applicability of soil-nailing composite pre-stressed anchor supporting wall, soil-nailing wall and row-pile composite pre-stressed anchor supporting structures in Lanzhou area.
