摘要
针对在软土地基上建造水闸时施工期存在温差、自生体积和干缩等变形,加上土压力、渗透压力和外部荷载等共同作用,闸体极易开裂甚至失稳,分析了水闸混凝土裂缝产生机理,可有效防止裂缝的产生。
When sluice is built on the soft soil foundation, it exist temperature difference, autogenous and dry shrinkages deformations during the construction period. At the same time, earth pressure, seepage pressure and external loads are combined action. Thus, it results in the cracks of sluice body easily and even causes the instability of the sluice. The mechanism of induced crack is analyzed and the cracks can be prevented successfully.
