| 摘 要： | 在工程建设中,软弱夹层是影响岩体工程特性的重要因素,因软弱夹层揭露后易松弛,且松弛速度快,通常情况下很难得到初始条件变形模量参数。通过在玄武岩地区百余米深的平洞内进行的原位特大型变形试验,在预留软弱带上部的保护岩层以防软弱带松弛条件下,得到软弱夹层与上部不同厚度盖层的综合模量。利用弹性力学的原理求得软弱夹层在深埋原位状态下的变形模量,研究结果表明软弱带在深埋条件下具有较高的变形模量。

| Abstract: | Weak zone is an important factor for the engineering characteristics of rock mass.However,once exposed,weak zone may get quickly relaxed,thus it is usually difficult to obtain the deformation modulus of weak zone from the initial conditions.Deformation experiment was conducted in a basalt area,to obtain the deformation modulus of the weak zone with the upper rock to prevent weak zone relaxation.By using the foundation of elasticity theory,the deformation modulus of weak zone on deep-seated condition was cal... |
