本文介绍华阳船闸施工排水量及由此而引起长江大堤沉陷量的计算以及在施工中所进行的观测;分析该工程施工降低地下水位对长江大堤的影响,并作出对江堤不会产生裂缝破坏的判断。说明在强透水性砂层中,采用深井降低地下水位是有效方法;降水不致引起地面构筑物或建筑物破坏。 This article introduces the construction displacement of Huayang shiplock and the calculation of the settlement of the Yangtze River dike caused by it, as well as the observation made during the construction. It analyzes the impact of the construction of the project to reduce the influence of groundwater table on the Yangtze River embankment and makes no damage to the dike Judgment. This shows that it is an effective method to use deep wells to reduce groundwater level in strong pervious sand; precipitation will not cause damage to ground structures or buildings.
