摘　　要：为分析软基水闸安全性态,采用三维激光扫描、地质雷达、钻探等多源手段对软基水闸进行多维度检测,并采用三维有限元对其结构和渗流安全进行复核。结果表明:①闸室结构未见明显不均匀沉降,两侧挡墙、闸墩和排架垂直度均在±2°以内;②水闸底板局部位置存在脱空,但规模较小;③水闸混凝土结构的耐久性以及桩基的有效性均满足设计和规范要求;④水闸渗流和结构安全均满足规范要求。In order to analyze the safety state of the soft-base sluice,multi-dimensional detection of the soft-base sluice was carried out by means of three-dimensional laser scanning,geological radar,drilling and other multi-source means,and three-dimensional finite element was used to review its structure and seepage safety.The results show that:①There is no obvious uneven settlement in the structure of the sluice chamber,and the verticality of the retaining walls,piers and bents on both sides is within±2°;②There is a void at the bottom of the sluice floor,but the scale is small;③The durability of the concrete structure of the sluice and the effectiveness of the pile foundation meet the design and specification requirements;④The seepage and structural safety of the sluice meet the requirements of the specification.
