Abstract

The surrounding rock pressure of vertical shafts is one of the basic parameters of shaft lining design. Investigating its calculation methods and applicable scopes has great engineering significance. The paper classifies and compares the calculation methods, discusses the application scopes of various calculation methods, and proposes that the axisymmetric layered method is highly consistent with the field monitoring data for the calculation of surrounding rock pressure of vertical shafts in bedrock sections on the basis of practical engineering examples. On the basis of Terzaghi theory, the calculation formula of surrounding rock pressure of vertical shaft in inclined rock strata with single group joints is derived. The formula can reflect the influence of rock strata dip angle and joints.

摘要

竖井围岩压力是竖井衬砌设计的基本参数之一。研究其计算方法和适用范围具有重大工程意义。本文对计算方法进行了分类和比较，探讨了各种计算方法的适用范围，并结合实际工程实例提出，对于基岩段竖井围岩压力计算，轴对称分层法与现场监测数据高度吻合。基于太沙基理论，推导了单组节理倾斜岩层中竖井围岩压力的计算公式。该公式能够反映岩层倾角和节理的影响。
