河北工程大学毕业设计(论文) -1- 河北工程大学 2008 级毕业设计片上水库土石坝枢纽毕业设计---------------- 黏土心墙坝设计方案专业: 水利水电工程班级: 08级 02班学号: 080290202 姓名: 蔡佳欢指导教师: 马文英 2012 年6月河北工程大学毕业设计(论文) -2- 摘要本文主要是片上土石坝枢纽的设计,片上水库是河海流域大清河北支流拒马河上的一座大(二)型综合利用水利工程。本工程等别为大二型,主要建筑物:拦河坝、溢洪道、隧洞、厂房、引水洞为 2级建筑物。枢纽的主要任务以灌溉为主,可为东部平原涞、涿灌区的一百多万亩农田灌溉、北京生活及工业用水提供水源。设计内容主要有: 1、对本枢纽工程,进行坝段、坝线及坝型选择、论证,并作出枢纽布置。 2、对选定的坝型,设计剖面,确定坝顶长度。包括最大剖面和特征剖面(不少于 3-5 个)。剖面内容包括:坝顶高程、坝顶宽度、上下游坝坡坡率,防渗体、排水体尺寸, 坝基防渗设施;坝顶长度用桩号表示。 3、对特征剖面(包括最大剖面)进行渗流分析。工况为稳定渗流期和校核洪水情况。分析内容包括单孔渗流量、浸润线坐标、总渗流量(化成 m3/ 昼夜)。 4、对稳定渗流期下游坝坡(基本组合,采用折线法、圆弧法)、不利水位上游坝坡(基本组合,采用折线法)、稳定渗流期+地震下游坡(特Ⅱ组合,采用折线法、圆弧法) 进行坝坡稳定验算。 5、设计大坝细部构造:坝顶构造、坝坡、防渗体及反滤层、排水体、截水槽、防渗墙、坝脚、马道等。关键字:挡水坝渗流计算稳定计算细部构造河北工程大学毕业设计(论文) -3- Abstract This paper isa design of earth-rock dam hub, on-chip Reservoir River Basin is in the Hebei branch of the Juma River ona large ( two) type multipurpose water conservancy project. This project donot for type two, main building: dam, spillway, diversion tunnel, tunnel, building2buildings. Hub main task mainly for irrigation, for the eastern plain real, Lai, Zhuo irrigation area of about one million acres of farmland irrigation, Beijing life and industrial water supply. Design is the basic requirements: 1, the project of dam, dam, and choice of dam type, argumentation, and make the project layout. 2, the selected dam type, design profile, determine the length of dam. Including the largest profile and characteristic profile (less than3-5). Profiles include: crest elevation, the top width, on the downstream slopes, impervious, drainage body size, dam foundation seepage prevention facilities; the crest length of pile. 3, the characteristic profile ( including the maximum section ) for seepage analysis. Conditions for steady seepage and check flood level. Analyses included single hole seepage flow, seepage line coordinate, total seepage flow ( to m3/ circadian ). 4, the period of steady seepage of dam slope ( essential mix, using broken line method, arc method ), adverse water level of upstream
