岩土复合地层双孔隧道开挖对地表沉降的影响
Influence of Double-hole Tunnel Excavation on Ground Settlement in Geotechnical Composite Stratum
摘要
Abstract
In order to study the influence of double-hole parallel tunnel excavation on ground settlement in geotechnical composite strata a calculation method based on complex variable function theory and stochastic medium theory is proposed and the influences of different tunnel excavation radius tunnel spacing and main influence angle of soil layer on ground settlement are discussed.The results show that a the calculation results considering geotechnical stratification are more consistent with the finite element results than those without stratification b with the increase of tunnel excavation radius the ground settlement increases c with the increase of tunnel spacing the maximum settlement value of ground decreases and the shape of settlement curve changes and d with the increase of main influence angle of soil layer the maximum ground settlement value increases and the width of ground settlement trough decreases.关键词
