岩石边坡风化与侵蚀的研究

Study on the Weathering and Erosion of Rock Slope

对岩石边坡的风化和侵蚀过程作了较为详细的分析和总结,发现岩石边坡的风化速度主要受岩性及构造、气候、岩体结构特性、岩面起伏及其裸露程度和人为因素的控制。此外也分析了岩石边坡侵蚀过程的机理及影响因素,随着冻融次数的增加,岩石的抗压强度显著降低。这些将为工程上治理岩石边坡的风化与侵蚀作用提供有价值的参考。

This paper gives detailed analysis and summary to the weathering and erosion process of rock slope, discovery the weathering velocity of rock slope is mainly controlled by such factors as lithology, structures, climate, structural characteristics of rock mass, the undulation and exposed area of rock surface, and man- made factor, furthermore, analysis the eroding mechanism of rock slope and its influencing factors. The result shows that the strength of rock evidently reduces with the increase of number of freezing and thawing cycle. These will be provided some valuable references to control the weathering and erosion of rock slope in engineering.
