| 摘 要： | 大连地区的土层结构较为复杂,在实际工程施工过程中,经常采用组合支护方式。在某工程中,通过进行对于两种情况下的基坑稳定性计算、支护方案设计以及后期施工效果的观测,验证了人工挖孔桩与劲性桩相结合、管式锚杆与锚索相结合、挂网喷射混凝土的联合支护方式对于复杂土层结构的深基坑支护具有良好的效果,是组合支护方式在大连地区深基坑支护中的成功应用。

| Abstract: | The combined support is usually used in the region of Dalian due to its complex ground structure.In one project,calculations,support designs and observations of the construction results have been carried out for foundation pit stability under different conditions,and it is proved that the combination of the hand-dug pile with the stiffness pile,the anchor cable with anchor bolt,and the woven net with sprayed concrete,provides better support for the foundation pit in complex ground,and also a successful field case in support of deep foundation in Dalian. |

| Keywords: | deep foundation combined support hand-dug pile stiffness pile anchor bolt anchor cable |
