摘　　要：堤防裂缝是堤防工程中常见的病害之一,若不及时治理,会影响到堤防工程的稳定和防洪安全。本文从堤防的应力分布、土层膨胀性、堤身土组成等方面探讨了句容市赤山湖湿地公园堤防道路纵向裂缝的成因。研究表明:裂缝多发生在拉应力深度内,土层具有弱膨胀性、堤身土组成存在差异、堤基存在沉降变形大的软弱土层是堤防纵向裂缝形成的主因。纵向裂缝可采取灌浆和开挖回填的方法进行治理,本文总结的纵向裂缝治理方法可为类似工程提供借鉴。The embankment crack is one of the common diseases in embankment projects. If the crack is not treated in time, it will affect the stability and flood control safety of embankment projects. The causes of longitudinal cracks in embankment roads of Jurong Chishan Lake Wetland Park are discussed from the aspects of embankment stress distribution, soil layer expansion and embankment soil composition, etc. The results show that the main causes of embankment longitudinal cracks include the soil layer weak expansibility, the difference of embankment soil composition and soft weak soil layer with large settlement and deformation in embankment foundation. The longitudinal cracks can be treated by grouting and excavation backfilling. The treatment method of longitudinal cracks summarized in the paper can provide reference for similar projects.
