| 摘 要： | 结合陈村重力拱坝原型观测资料，对带缝坝体异常变形成因进行分析。研究表明：陈村拱坝１０５裂缝扩展、左坝肩基岩相对软弱、大坝所处高温低水位不利运行工况以及坝体特殊结构型式是产生异常变形的原因。建议实际运行时应调控水位，避免不利运行工况。

| Abstract: | In the light of the prototype observation data of Chenchun gravity arch dam,the causes of the unusual deformation of the dam with cracks are analysed.The research shows that the opening of crack El.105m the relative soft and weak bed rock of the left abutment,unfavourable operation conditions-high temperature and low water level and the special structure of the dam can be regarded as the causes of unusual deformation.It is necessary to take measures to control the water level to avoiol unfavorable operation conditions. |
