| 摘 要： | 桩锚支护和复合土钉墙支护等是基坑支护的常用方案，从经济性和控制变形效果来看二者各有优缺点。通过工程实例，探讨了深厚砂层等复杂环境条件下既安全又经济的土钉墙与竖向微型桩、预应力锚杆等结合组成的基坑支护方案，并通过变形监测数据验证其支护效果。

| Abstract: | Pile-anchor retaining and compound soil nailing support are the common schemes for the foundation pit supporting. In the view of the economy and deformation control, each scheme has its advantages and disadvantages. With the engineering case, the discussion was made on the safe and economical supporting scheme by composition of soil nailing wall with vertical micro-pile and pre-stressed anchor, and the supporting effect was verified by the deformation monitoring data. |

| Keywords: | complex conditions deep and thick sand layer foundation pit supporting soil nailing wall vertical micro-pile pre-stressed anchor |
