针对我国立井井筒设计规范建议的径向荷载计算方法的准确性与适用性问题,基于多个立井工程的地质资料及参数,根据规范方法计算得到其径向荷载的理论分布特征,并与实测数据进行了比较。结果表明,规范建议公式的计算结果与实测值存在一定的误差,尤其是计算岩层中的井壁径向荷载误差较大,且立井深度越大,基于规范算法得到的井壁径向荷载误差越大。由此建议深入开展深土力学研究,基于更多的测试与研究来确定深厚表土中井壁径向荷载的大小与分布规律。
According to the accuracy and applicability of the radial load calculation method proposed in China’s shaft design code, the theoretical distribution characteristics of radial load are calculated based on the geological data and parameters of several vertical shaft projects and compared with the measured data Compared. The results show that there is a certain error between the calculated results and the measured values. Especially when the borehole radial load in the rock strata is relatively large, and the vertical well depth is larger, the error of the radial borehole wall based on the canonical algorithm Big. Therefore, it is suggested that deep soil mechanics research should be carried out in depth, and based on more tests and studies, the radial wellbore radial load in deep topsoil should be determined.
