摘要
据野外调查,广州南部南沙是软土地基沉降地质灾害的典型地区。为系统掌握软土沉降变化规律及准确分析致灾原因,拟采用多种技术手段对南沙地区的软土沉降进行监测。一方面可以系统评价各种技术手段的精度、适用范围、效率和成本等特点,以便选择最优技术手段进行监测;另一方面可以全面系统地对比分析监测数据,科学客观地找出软基地面沉降的规律和系统分析软土地基沉降形成机制及相关因素。
According to field investigation, Nansha in southern Guangzhou is a typical area where soft soil deposits geological disasters. In order to systematically grasp the rule of soft soil subsidence and accurately analyze the causes of disaster, we used various technical means to monitor soft soil subsidence in Nansha. On the one hand, it was possible to systematically evaluate the accuracy, scope of application, efficiency and cost of various technical means in order to select the optimal technical means for monitoring. On the other hand, we could analyze the monitoring data systematically, find out the rule of soft ground subsidence scientifically and objectively, and analyze the formation mechanism and related factors of soft ground subsidence.
