摘要
通过建立的等效模型,从理论上分析了层面厚度对双向异弹模的影响及双向异弹模对位移的影响,并基于工程实例进行了计算。结果表明双向异弹模对水平位移和竖向位移都有较大的影响,竖向弹模对水平位移和竖向位移的影响要比横向弹模大,横向与竖向弹性模量的比值愈大,影响也愈大,且影响程度随横向弹模的增大而减小。在位移监控指标的拟定时应给予考虑。
A equivalent model is established to analyze influence of RCCD layers' thickness on elastic modulus and two-way different elastic modulus on displacement. The results of theoretical analysis and case calculation show influence of transverse elastic modulus is less than vertical, change of displacement is consistent with change of proportion between transverse and vertical elastic modulus, and big transverse elastic modulus decreases influence degree. Influence of two-way different elastic modulus on displacement should be considered when monitoring index drafted.
