| 中文摘要:拟建北京市第55中学地下食堂与北侧教学楼地下室结构紧贴，地下食堂基坑北侧受场地限制，没有施工护坡桩空间。然而，土钉墙支护不能满足周边环境对基坑位移和沉降的严格要求。针对上述问题，设计采用了嵌入式“预应力锚杆 肋板墙支护结构”代替桩锚支护结构。结合该基坑支护工程的实例，介绍了预应力锚杆肋板墙支护结构的参数设计和施工技术措施。 |

| Abstract:The underground canteen of Beijing No.55 Middle School is adjacent to the basement structure of a classroom building at the north side, no space was remained for retaining pile because of the site restriction in the north of underground canteen foundation pit, and soil nailing wall support cannot meet the strict requirements of surroundings on the displacement and settlement of excavation. In this case, an embedded “pre-stressed anchor ribbed plate wall” was designed and adopted to replace the pile-anchor support structure. Combined with the engineering case of foundation pit support, this paper introduces the parameters design and construction measures for the pre-stressed anchor and ribbed plate wall structure. |
