1、斜心墙土石坝人行梯步设计规范篇一：斜心墙土石坝初步设计中文摘要某江河位居于我国西南地区，在该江中上游建造以斜心墙土石坝为挡水建筑物的水利枢纽。水利枢纽以防洪为主要任务，以发电、灌溉等为该地区创造经济价值。本毕业设计侧重于拦河坝段斜心墙土石坝的挡水建筑的初步设计。首先，应用该枢纽的各项具体数据，来确定出工程等级和建筑物的等别。调洪方案初步拟定后，应用列表计算来确定出设计洪水位、校核洪水位、设计泄洪量、校核泄洪量。随后针对土石坝各种坝型方案进行定性分析比对，最终选择斜心墙土石坝。初步拟定出斜心墙土石坝的剖面尺寸后，取其三个特征剖面进行渗流计算，校核渗透逸流处的渗透坡降是否满足要求。本毕业设计采用折
2、线法的VB编程进行斜心墙土石坝的稳定分析。最后，对坝体的细部构造进行设计。本设计以碾压式土石坝设计规范DL/T5395-20XX为基本设计依据。此外参考了与土石坝的有关资料和书籍。由于知识有限，对于本设计中的不妥及错误之处，恳请批阅批评指正。关键词：斜心墙土石坝 渗流计算 稳定分析 毕业设计AbstractA river in southwest China ranked, built oblique core embankment of retaining water control structures in the upper reaches of the river.
