题型：多项选择题 根据河流规划拟在A江建设一水利水电枢纽工程，该枢纽工程位于西南地区。工程以发电为主，同时兼有防洪、灌溉等任务。挡水建筑物为土石坝，水电站采用引水式开发方式。引水隧洞布置在右岸，在左岸设有开敞式溢洪道。该流域大部分为山地，山脉、盆地相互交错于其间，地形变化大。坝址地区河床覆盖层厚度平均20m，河床冲击层为卵砾石类土，但河床宽度不大。坝址两岸山坡陡峻，为坚硬的玄武岩。在坝址的上下游2km内有可供筑坝的土料190×104m3作为防渗体用，另有1250×104m3的砂砾料可用作坝壳料。由于本地区黏性土料天然含水量较高，同时考虑其他因素，土石坝设计方案选为斜墙坝。 [问题]1．在初步设计文件里，采用了分段围堰法导流，明渠导流方案。你认为此方案是否合理若合理，请分析说明理由；若不合理，你认为应如何选择导流方案 2．针对该土石坝施工，你认为如何做好料场规划 3．作为项目经理，如何安排斜墙和反滤料及坝壳的施工 查看答案
