8、置较长，且在隧道内有曲线，即使从垭口过，所需设置的隧道也较长，填挖方量特别大，工程量和工程费用都比较大。二方案：线路从笔湾下方山地，沿着珠河支流展线，多设置涵洞，在笔湾开始打隧道，线路从马家下面通过，避免再次展线，再穿越中河沿丘陵地段到达理店，最后横跨后河到达B站。该方案在从珠河站出来，进入笔湾后方的山地时所需克服的高程较大，地形坡度较紧，填挖方量较大。但中段隧道相对较短，工程量相对较小且地形便于展线。三方案：线路从张村上方山地，沿珠河平行的支流展线，过两山间的垭口到达陈庄下方，从曾溪上方横跨中河，经孙家坎沿后河支流到后河镇。该方案前段的地形便于展线，隧道特别短，可以用足限制坡度，减少隧道长度
9、，土石方运量。但是大量穿越丘陵地区和山间河谷，线路大大加长，工程量巨大。虽然节约了隧道费用，但沿线的大量展线费用大大加大。进入张村后方的山地时所需克服的高程较大，地形坡度较紧，填挖方量较大，但所选隧道相对较短。后段线路较平顺，沿河谷地段高程变化不大。此线路相对较长，展现系数大，而且线路转折多，曲线设置较密集。综上：考虑到隧道的施工量较大，造价高，为该线路的控制工程，经过综合比选，确定方案二比较适合。虽然其填挖方量相对来说是最大的，但是第一，该方案曲线数量较少，曲线转角不大，曲线在整条线路中所占的比例也比较小；第二，该方案的隧道相对来说比较短，工程量可减小；第三，该方案沿途经过的居民区较较少，可
10、减少噪音，震动等对沿线居民生活的不良影响，减少所占用的农田和耕种土地。线路基本上沿航空直线，线路较短。6、 选定方案定线说明1、定线原则：缓坡地段只要注意绕避平面障碍，按短直方向定线。紧坡地段线路不仅受平面障碍的限制，更主要的是受高程障碍的控制，所以选线时需要根据地形变化情况，选择地面平均自然坡度与最大坡度基本吻合的地面定线，有意识地将线路展长，使其能达到预定高程。2、平面设计：（1） 定线说明：平面共设曲线4处，其中最小半径为800米。（2） 平面主要技术指标：平面设计技术指标表项目单位线路指标正线线路总长km12.175曲线个数个4曲线线路延长km3.07曲线占线路总长比例0.25最大曲线
