崩塌作用

崩塌作用对工程爆破效果影响的研究

Study on the Influence of Collapsed Action Upon Engineering Blasting Effect

喀斯特洞穴是喀斯特地貌的重要组成部分，在地质营力溶蚀，侵蚀和崩塌作用下形成。

Karst cave , an important component of karst geomorphology , is formed by geological agent corrosion , erosion and collapse .

结果表明，La有抑制分子筛骨架脱铝和结构崩塌的作用。

Results showed that La is effective in making zeolite more resistant to structure collapse and aluminum removal .

讨论了粘性土在不同固结状态下的强度指标变化规律，阐述了土的强度指标对滑坡稳定性的影响，以及雨水对滑坡崩塌滑动的诱发作用。

The influence of the soil shearing strength index on slope stability is recommended , and the inducing factor of rainfall on formation cracking and slip failure in the surface of slope is presented .

强烈的下切作用为岸坡孕育小范围崩塌提供了必要的势能累积与临空面，另外，侧蚀作用进一步加剧了岸坡崩塌作用。

Cutting action under the strong small-scale collapse of the slope provides the necessary potential energy accumulation and free surface . In addition , the side etching effect exacerbates the slope collapse .
