摘　　要：根据15年的监测成果,对施工及运行期高边坡和船闸的变形、渗流和应力应变等进行分析。结果表明:高边坡变形主要受开挖卸荷的影响,开挖结束后变形速率减缓,并逐渐趋于稳定;船闸变形主要受水压、气温和时效影响;高边坡和船闸渗流渗压较小,说明高边坡经过采取截、防、排水等措施后,防渗效果显著;高边坡和直立墙经过喷锚支护、锚杆和预应力锚索加固,限制了高边坡的变形。目前高边坡和船闸处于稳定状态。According to the result of 15 years monitoring,the deformation,seepage and stress-strain of the high slope and the navigation lock during construction and operation periods are analyzed.The deformation of the high slope is mainly affected by the excavation unloading and slows down and stabilizes gradually after the excavation.The navigation lock deformation is mainly caused by water pressure,temperature and aging.The seepage and the seepage pressure of the high slope and the navigation lock is relatively smaller,which shows that the effect on preventing the seepage is notable by taking measures of interception,prevention,drainage and so on.The deformation of the high slope has been limited after reinforcement for high slope and vertical wall with spray-anchor,anchor bolt and pre-stressed cable reinforcement.At present,the high slope and the navigation lock is in a stable state.
