rock-fall earthquake

Evaluation of the permanent displacement of rock mass slope considering deterioration of slide surface during earthquake

考虑结构面退化的岩质边坡地震永久位移研究

If you are in a mountainous area, or near unstable slopes or cliffs, be alert for falling rock and other debris that could be loosened by the earthquake.

如果你在山区，或是在不稳定的斜坡或山崖旁，注意那些因地震而从山上滚落下来的岩石和其它山体残骸。

A new approach for evaluating the permanent displacement of rock mass slope including planar slide and wedge slide during earthquake was presented, which considered deterioration of slide surface during earthquake.

针对岩质边坡平面滑动问题和楔形体滑动问题，提出了一种考虑结构面退化的岩质边坡的地震永久位移算法，提供了该法实施的流程，并用3个实例进行了说明。

The main loads leading to collapse of dangerous rock are gravity, water pressure and earthquake force.

重力、水压力、地震力是危岩崩塌的主要荷载。

Large earthquake-induced rock avalanches , soil avalanches , and underwater landslides can be very destructive.

大地震造成的岩石、土壤崩塌，以及水下滑坡破坏性极大。

The Testing of Earthquake Effect Caused by Blasting in Bedded Rock

层状岩体爆破地震效应的测试

Comprehensive analysis, the left bank of the V# ridge "rock wall" after excavation of slope stability factor of the higher, the most adverse conditions ( rain+ earthquake) as 1.4888, the slope at steady state.

综合分析，左岸V山梁岩墙边坡开挖后的稳定性系数较高，最不利工况（暴雨+地震）为1.4888，边坡处于稳定状态。

The ground subsidence causes the special damages: earthquake of collapse, forming of moving trough basin and rock falling and slipping.

它们造成的特殊危害分别有塌陷地震、形成槽形移动盆地和产生崩塌、滑坡。

This text utilizes finite element method set up slope rock deep hole blasting models of some power station, use three-dimensional finite element entity unit model, and make time history analysis when going on of blasting earthquake.

并利用有限元方法建立了边坡岩石深孔爆破模型，爆破地震的产生过程进行模拟，获得距爆孔一定距离范围内岩体某点的加速度时程曲线，即取得了爆破地震波。

The fracturing of initial rock mass is another mechanism of tectonic earthquake.

完整岩体压剪破裂失稳是构造地震的另一种可能孕震机制。
