摘要
因取材方便、能适应各种不同的地形地质气候条件等优点,土石坝成为实际工程中最为常用的一种坝型。综合技术经济比较后,阆中市华儿湾水库确定了合理的坝轴线和土石坝坝型。结合地形地质条件,前期设计中优化了坝体断面及分区。施工过程中处理了坝基地质缺陷、修正了坝壳料填筑指标,并初步探讨了坝基灌浆单位水泥耗量超定额的问题。
Earth-rock dam has become the most commonly used dam type in practical engineering because of its advantages of convenient materials and adaptability to different terrain,geology and climate conditions.After comprehensive technical and economic comparison,the reasonable dam axis and earth-rock dam type of Hua'erwan Reservoir in Langzhong City were determined.According to the terrain and geological conditions,the section and zoning of the dam body were optimized in the preliminary design.In the construction process,the geological defects of dam foundation were dealt with,the filling index of dam shell material was corrected,and the problem that the unit cement consumption of dam foundation grouting exceeds the quota was preliminarily discussed.
