摘　　要：为保证大连某水工护岸的景观效果,须将水下圆筒的倾斜控制在一定范围内。因此基于理论计算方法,在施工现场3个区段分别采用不同加载方案进行加载试验,积累了大量现场实测数据,并获取了圆筒两侧不均匀荷载引起圆筒倾斜发展的关键数据。通过分析该工程3种加载应力路径下圆筒倾斜发展的规律,提出在结合工期要求下,配合一定的倾斜治理措施,适当加快施工节奏的思路。The tih data of cylinder caisson should be controlled within certain limits for a better landscape of a hydraulic revetment in Dalian.Therefore,different loading tests were carried out in three regions of construction site according to the theoretical calculation method.Thus, a great deal of experiment data had been accumulated, and the key data of cylinder caisson tilt caused by uneven loads was obtained.Based on the law of cylinder caisson tilt under different stress paths, appropriate measures to accelerate construction pace on the basis of time limits of project were proposed together with tilt control measures.
