摘要
北京山区地质复杂,工程频繁,边坡灾害发育以崩塌和滑坡为主。边坡灾害以岩质边坡和人工边坡为主,破坏模式为剥落、落石、崩塌和滑坡。从地质构造、地层岩性、气候条件和人类活动4个方面分析边坡灾害的影响因素,提出对应的防范措施。
Collapses and landslides are the main slope disasters in Beijing mountains due to complex geology and frequent engineering activities.The disasters mostly happen to rock and artificial slopes,and their failure modes are spall,rock fall,collapse and landslide.Their influencing factors are analyzed from tectonics,lithology,climate and human activities,and preventive measures,accordingly,are proposed.
