摘　　要：珠海市软土分布广泛,随着近年来经济建设的快速发展,软土沉降问题已成为制约珠海经济发展的突出环境地质问题。通过地质、工程相关资料,总结出珠海市软土分布特征,并从地质环境条件、沉降现状、人类活动和社会经济条件4个方面着手,利用层次分析-综合指数法对珠海市软土沉降风险性进行评价。最后根据评价结果,提出针对性防治建议,为珠海市国土空间开发利用与城镇规划提供地学依据。Soft soil is widely distributed in Zhuhai.With the rapid development of economic construction in recent years,soft soil subsidence has become a prominent environmental geological problem restricting the economic development of Zhuhai.Based on the data of Geology and engineering,this paper summarizes the distribution law of soft soil in Zhuhai.With four aspects of geological environment conditions,settlement status,human activities and social and economic conditions,this paper uses AHP comprehensive index method to analyze the risk assessment of soft soil subsidenc in Zhuhai.Finally,according to the evaluation results,the paper puts forward some suggestions for prevention and control,which can provide geoscience basis for the development and utilization of land space and urban planning in Zhuhai.
