一、工程概况东武仕水库位于河北省磁县滏阳河干流上。土坝为辗压式均质坝,最大坝高33.3米,坝顶长2665米。大坝于1959年建成,1970年扩建,在上游面填土补坡将坝体加高5.7米。1980年又计划将坝高再增加1.5米,并已做了设计,尚未动工。坝基土层为粉质壤土、粉细砂、中砂等多种土层交错互生,系由历史上多次洪积、坡积、残积等地质作用生成。土的天然孔隙比一般在0.66以上,密实度低。这给抗震保坝加固
First, the project overview Dongwu Shi reservoir in Cangyang County, Hebei Province, the main river Yang. Earth dam is rolling homogeneous dam, the maximum dam height of 33.3 meters, 2665 meters long crest. The dam was completed in 1959 and expanded in 1970. The dam was raised 5.7 meters in the upper part of the dam. In 1980, the dam height is planned to increase by another 1.5 meters and the design has been done yet. Dam foundation soil is silty loam, silty sand, sand and other soil layers alternately alternate, by the history of many alluvial, slope plot, residual and other geological effects generated. The natural porosity of the earth is generally above 0.66, with low density. This reinforces the earthquake-resistant dam
