Different critical horizontal stress is put forward under the different loading condition through studying the influence of different lateral loading coefficient on the rock burst occurrence.

在此基础上研究了不同侧向加载系数对发生冲击的影响,提出了在不同加载条件下,冲击时存在不同的临界水平应力;研究了不同的煤岩组合情况对发生冲击的影响,得出了底板中存在着相对硬软的岩层是发生底板冲击的一个必要条件。

Combining with the engineering practice in Nanjing and empirical formulas at home and abroad,the calculating method of the critical horizontal stress index(K_(Dcr)) is put forward;moreover,the liquefaction estimation and calculation of liquefaction grade are made by this method.

结合南京的工程实践和国内、外的经验公式,提出了临界水平应力指数(KDcr)的计算方法,并以此来进行液化判别和计算液化等级。
