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 FEM to simulate and calculate.That is successfully applied in engineering,achieving g...
