针对压力型锚索设计的理论方法是建立在均质岩体的这一假设,考虑到实际工程中风化岩体是非均质且连续的这一特性,结合横观各向同性体在点荷载作用时的应力特征,推导了压力型锚索在风化岩体内的剪应力表达式,并在此基础上建立了压力型锚索锚固长度的设计方法,使修正后的设计方法更加符合实际工程。通过数学回归方法获得了实际工程的物理参数,采用修正后的设计方法进行了算例分析,结果表明修正后的设计方法非常符合实际工程情况。
The theoretical method for the design of pressure-type anchor cable is based on the assumption of homogeneous rock mass. Considering the fact that the weathered rock mass is heterogeneous and continuous in practical engineering, in combination with the effect of transversely isotropic mass on point load The stress characteristics of the pressure type anchor cable are deduced, and the shear stress formula of the pressure type anchor cable in the weathered rock mass is deduced. Based on this, the design method of the anchorage length of the pressure type anchor cable is established, which makes the revised design method accord with the actual project. Through the mathematical regression method, the physical parameters of the actual project are obtained. The modified design method is used to carry out the case study. The results show that the revised design method is in good agreement with the actual engineering conditions.
