摘要
摘要:随着社会经济的发展，人类工程活动日趋强烈，中山市崩塌、滑坡地质灾害呈加剧趋势。根据中山市1：50000地质灾害详细调查数据，结合中山市环境地质特征，对中山市崩塌、滑坡地质灾害的发育规律进行了分析。统计分析表明，4~9月是汛期雨季，是中山市崩塌、滑坡地质灾害的高发季节。崩塌、滑坡地质灾害多发生在坡高10~30 m的斜坡带上，均分布于山体坡脚，临近居民区及建筑物，与人类工程活动密切相关。本地区崩塌、滑坡地质灾害具有突发性强、规模小、危害性大等特征，为中山市今后崩塌、滑坡地质灾害防治工作提供基础依据。

Abstract:With the development of social economy, the human engineering activities become more and more intense, and the geological disasters of Zhongshan City collapse and landslide become more and more serious. Based on the detailed survey data of 1 ︰ 50000 geological disasters in Zhongshan City and combined with the environmental geological characteristics of Zhongshan City, this paper analyzes the development law of landslide and landslide geological disasters in Zhongshan City. Statistical analysis shows that from April to September is the flood season and rainy season. Most of the geological disasters of collapse and landslide occur in slope zones with slope height of 10~30 m, which are distributed at the foot of slope, close to residential areas and buildings, and closely related to human engineering activities. The geological disaster of collapse and landslide in this region is characterized by strong suddenness, small scale and great harmfulness, which provides the basis for the prevention and control of the geological disaster of collapse and landslide in Zhongshan City in the future.
