青岛市地质灾害现状和风险评价

Present Condition and Risk Evaluation of Geological Disasters in Qingdao City

摘要:

青岛地质环境条件较复杂，地质灾害隐患点较多，规模主要为小型。已发现的地质灾害种类有崩塌、滑坡和地面塌陷等3种，其中以崩塌为主，地面塌陷次之。地质灾害的形成受到内、外在因素及人类工程活动的影响。总结每个地质灾害隐患点的规模大小、威胁对象、危害程度、发育时间等特征，概算出危险度和易损度，确定灾害风险度，提出防治建议，为地质灾害防治工作提供科学依据。

Abstract:

Geological environment in Qingdao city is complicated. There are many hidden dangers in geological hazards with small scale mainly. The already discovered: geological hazards are collapse, landslide and ground collapse. Among them, collapse is the main, and followed by ground collapse. The formation of geological hazards is influenced by internal and external factors and human engineering activities. The scale, threat object, harm degree, and development time of each geological disaster potential points have been summarized, risk and vulnerability have been estimated, disaster risk has been determed, and prevention and control countermeasures have been put forward. It will provide scientific basis for prevention and control of geological disasters.
