| 摘 要： | 利用三维有限差分程序,研究了静止侧压力系数K0及各向异性模量比值n对隧道施工引起的地表下沉位移的影响.结果表明:Pcck公式的预测值比FLAC3D所得到的地表最大下沉位移值要大,且横向沉降槽的宽度较窄;地表最大下沉位移值随各向异性模量比值n的增大而增大,且横向沉降槽也随之变宽,而静止侧压力系数K0对地表最大下沉位移的影响则反之.

| Abstract: | The influences of static lateral pressure coefficient K0 and anisotropic modulus ration on surface subsidence and displacement induced by tunnel construction were researched by using three-dimension explicit finite-difference program.Some conclusion can be drawn:the maximum subsidence values predicted by Peck method was larger than that by FLAC3D,and the width of transverse settler was narrower.The maximum subsidence and displacement values increased along with the increase of anisotropic modulus ration,and... |
