摘要
本文通过岩石三轴抗的炕压试验表明，随着设计围压的增大，屈服极限和强度极限均有限均有规律地增大。因此，在受到同等水平挤压的情况下。盖层埋深越大，岩石的抗剪抗压强度越大、越不易产生犁缝。作者结合实际钻探实例，根据水文地质垂直升帝与盖层埋深的关系，得出了具体评价区域盖层条件的定量标准。
The experimental analysis of triaxial resistance to shearing and compressing on rocksshow that yleld limit and ultimate tensile strength would increase regularly along with theincrease of design confining pressure. Futhermore,in a case of same compressional force. the deeper the buried depth is for the coveriiig strata, the higher resistance to the shearing and compression strength would be for the rocks, and the less the fractures would be gen-erated.With the combination of case studies of practical explorations, the authors setquantitative standards to estimate regional covering strata, based on the relationship of vertically hydro一geologic zoi1ing with the buried depth of a covering strata.
