摘　　要：本文以天津市武清区崔黄口镇、南蔡村镇,北辰区青光镇示范小城镇地质环境背景为例,开展地质灾害调查,评估地质灾害危险性。结果表明:地层结构较简单,分布较连续,厚度较稳定,稳定性较好,适宜建筑物的兴建;主要地质灾害为地面沉降、砂土液化和水土腐蚀;青光镇地质灾害危险性大,南蔡和崔黄口危险性中等;地面沉降虽有较大的危害,但可采取适当措施予以预防控制。Based on the geological environment background,this paper carries out geological disaster investigation and evaluates the risk of geological disaster.The results show that the stratum structure is simple,the distribution is continuous,the thickness is stable and the stability is good,which is suitable for the construction of buildings;The main geological hazards are land subsidence,sand liquefaction and water and soil corrosion;Qingguang Town has a high risk of geological disasters,and Nancai and Cuihuangkou have a medium risk.Although land subsidence has great harm,appropriate measures can be taken to prevent adverse effects.
