| 摘 要： | 地下空间的开发和利用是当前岩土工程发展的重要趋势之一.地下洞室是开挖在岩土体中作为各种用途的构筑物,地下开挖后,破坏了岩土体天然应力的相对平衡状态,引起围岩应力的重新分布,因此,地下洞室稳定性分析的重要内容之一是确定围岩应力的大小.围岩应力受诸多因素的影响,松动圈是重要的影响因素之一.文中比较详细地介绍并分析多种松动圈的确定方法,并对各种方法的优缺点进行简要评述,同时介绍了未来研究的方向. |

| Abstract: | The development and exploitations of underground space is one of the important trends of Geotechnical Engineering.Underground cavities are some kinds of useful structures which are built in rock or soil.The cavities break the balance of the natural stress.They make the stress to come to a new balance.One of the important ways that analyze the stability of underground cavities is how to make out the stress of surrounding rocks.There are many factors which can influence the stress of surrounding rocks.Broken ... |
