rock subsidence

Through the medium of expound surface subsidence mechanism, analyses underground rock mass states of in-plane stress and underground opening spatial establishment.

通过阐述地面沉陷机理，分析地下岩体内应力状态和地下开挖空间的形成过程。

Evaluation on Structure Damage Due to Heavy Rain in Hard Composite Rock-mass in Subsidence Area

暴雨入渗对复合岩体塌陷区结构失稳的影响

There exists a cause effect chain among underground mining, rock movement and surface subsidence.

地下开采-覆岩移动-地表沉陷之间存在着互为因果的链动关系.

Through theoretical analysis and laboratory tests the main conclusions of research is as followed: It is effective to implement back filling technique in caving zone and breaking zone, control overburden rock mining subsidence, eliminate surface subsidence and protect the safety of the surface buildings.

通过理论分析和实验室试验，得出：实施垮落带和裂隙带注充技术可有效的控制覆岩采动下沉，消除地表沉降，保护地表建筑物、构筑物的安全。

The main kinds of the geological disasters are water loss and soil erosion, expansive soil hazards, rivers bank collapse, ground subsidence, water and soil pollution, landslide, debris flow, seawater intrusion, rock desertification in rocky area, etc.

广西主要地质灾害有水土流失、膨胀土地质灾害、河岸崩塌、地面塌陷、水土污染、滑坡、泥石流、海水入侵、山区石漠化等。
