1. 工程概述
1.1 概况
马马崖一级水电站位于北盘江干流（茅口以下）中游，花江大桥上游20.2km处的关岭县尖山村和兴仁县补朗村交界的尖山峡谷河段，其上游45km为已建成的光照水电站，下游依次为规划的马马崖二级水电站和刚建成的董箐水电站。电站距贵阳市公路里程207km，距六盘水市203km，距兴义市140km。电站附近现有S210省道及贵昆和南昆二条铁路通过，对外交通十分便利。
工程任务以发电为主，航运次之。电站装机容量540MW，安装三台单机容量为180MW的水轮发电机组。马马崖一级水电站属二等大（2）型工程。
引水系统采用一洞一机供水方式，单机引用流量304.2m3/s。坝身式进水口前沿总宽度为75.20m，底板高程为549.00m，设一道检修门和一道快速事故门。三条引水隧洞平行布置，轴线方位由NE78o通过竖井转为方位SE26o，内径9.75m，3条引水隧洞长度分别为220.632m、265.173m、307.127m。压力钢管为16MRn，内径为8m，3条压力钢管长均为41.893m，与地下厂房纵轴线成75°交角斜向进入厂房。
地下厂房洞室群布置于大坝左岸山体内，厂房纵轴线方位为N79oE，厂区枢纽建筑物主要由主厂房、副厂房、主变洞、母线洞、厂坝电梯井、出线平洞、出线竖井、排风洞、进风洞、进风竖井、排水廊道、厂变交通洞、主变交通洞、主变交通廊道等地下洞室和地面开关站组成。主厂房由主机间和左安装间组成，主机间长76.5m，机组间距24.5m，岩锚梁以上开挖宽度24.9m，以下开挖宽度23.3m，机组安装高程500.90m，顶拱开挖高程542.80m，尾水管底板开挖高程480.0m，最大开挖高度62.8m。安装间长45.0m，宽23.3m，高24.8m。副厂房位于主机间右侧，长19.0m，宽23.3m，高24.8m。主变洞平行布置于主厂房下游侧40.0m处，长80.0m，开挖宽度15.3m，高16.2m。3条母线洞位于主厂房和主变洞之间，长40.0m，净断面空尺寸6.5m37.0m。开关站位于主变洞上方的地面缓坡地带，底板高程605.30m，平面尺寸80m328m（长3宽），高压电缆从地下主变洞通过出线竖井和出线平洞通至地面开关站。在主厂房和主变洞周围10m～25m处布置两层平面上呈封闭形式的排水廊道，顶层排水廊道长660m，底板高程为542m～535.3m，
