| 中文摘要:深基坑工程支护体系施工存在较多难点，在复杂地层下施工，要结合现场实际情况灵活选取相适应的施工方案。在太原万达广场B2区基坑支护工程施工中，现场遭遇流砂地层后，常规锚索支护出现施工难点，改用扩大头锚索工艺后有效控制了涌水、涌砂现象，最终常规锚索与扩大头锚索结合使用效果显著，确保了支护结构的安全，减少了对临近建筑物的影响，降低了基坑支护的成本。 |

| Abstract:There are many difficulties in the construction of deep foundation pit support system. In the complex formations, the suitable construction scheme should be selected flexibly according to the actual situation on site. Quicksand stratum was encountered in a foundation pit supporting construction in Taiyuan, the extended end anchorage cable took was used in stead of the conventional anchor cable, and groundwater and sand inflow were effectively controlled. The combined use of conventional anchor cable and the extended end anchorage cable has remarkable effect, which ensures the safety of supporting and retaining structure, reduces the influence on adjacent buildings and reduces the cost of foundation pit support. |
