When the foundation pit project is completed, the temporary supporting structures, such as anchor bolt and sprayed concrete, are buried in underground. These not only change into the underground junk, also affect the development and utilization of adjacent underground space. This paper attempts to use the wood nails instead of anchor in shallow foundation construction as a temporary supporting structure, using the MIDAS GTS4.0 3D FF.M to simulate and calculate. That is successfully applied in engineering, achieving good economic and social effect.%在基坑工程完成后,锚喷支护等临时围护结构都被掩埋在地下,形成地下空间垃圾的同时,影响临近地下空间开发利用.文章尝试用松木钉代替锚杆在浅基坑施工中作为临时支护结构,通过用MIDAS GTS4.0有限元三维模拟计算后,在工程中成功运用,取得不错的经济、社会效果.
