摘　　要：深圳软件园工程,基础开挖土体为杂填土、粘土和淤泥,基坑边坡稳定性差,设计采用土钉和深层搅拌桩止水帷幕相结合的复合土钉支护,并详细介绍了土钉墙手工计算过程,提出了复合土钉支护设计时须考虑其组成要素的综合作用,不同地层条件下,结果作用发挥程度不同。In Shenzhen Software Park project, the foundation excavation soil is a mixture of miscellaneous fill, clay and silt, and the foundation pit slope has poor stability, so composite soil nail support combining soil nail and deep mixed pile waterstop curtain together is designed and adopted. Manual calculation process of soil nail wall is introduced in details. It is advanced that combined effect of all elements must be considered during design of composite soil nail support, because there may be different functional effects on different stratums.
