摘要
地面沉降已经发展成为天津市的主要地质灾害之一,不均匀的地面沉降已经给天津市河道堤防的安全造成了威胁,部分堤段已经出现了裂缝、漏洞等险情。为有效控制堤防工程的地面沉降,以海河干流堤防和蓟运河下游堤防为例通过对长序列的地面沉降数据进行分析,阐述了地面沉降对河道堤防造成的影响,并针对地面沉降对堤防工程造成的破坏提出相应的治理措施,保障工程的功能效应,减小堤防工程因地面沉降而产生的经济损失。
Land subsidence has developed one of the main geological hazards in Tianjin.Differential ground settlement has threatened to the safety of the embankment which has fissures and leakage funnels.For purpose of controlling the subsidence of the embankment,the effects of the subsidence are discussed with two case studies which are embankment of Haihe River and lower reaches of Jiyunhe River using long-term data of the subsidence.Some countermeasures are suggested to protect the function of the embankment and to decrease the losses caused by the subsidence.
