摘要
以某高填方软弱地基为对象,在阐述刚度理论的基础上,分析了不同弹性模量、不同桩径对填方路堤沉降的影响规律.模拟结果表明各工况下路面沉降均表现为中间大两边小的变化趋势,弹性模量越小,路面差异沉降越大.搅拌桩弹性模量增大或桩径增大的情况下,路面的最大沉降差均逐渐减小.最后从路面沉降的客观规律入手,分析了改善路面差异沉降的思路并进行了验证.
Abstract
Based on a high-filled soft foundation,this paper analyzed the influences of different elastic moduli and pile diameters on the settlement of the filled embankment according to the statement of the stiffness theory.The simulation results indicated that the road settlement under each working condition showed a trend of large in the middle and small on both sides.The smaller the elastic modulus,the larger the surface differential settlement.When the elastic modulus of the mixing pile or the pile diameter increased,the maximum settlement difference of the road surface gradually decreased.Regarding the objective law of road settlement,this paper analyzed and verified the principle of road differential settlement.
