DIyK39+575(右线)=GK0+112.0铁路跨线桥施工方案优化一、编制依据及采用规范1、《公路桥涵设计通用规范》（JTG D60-2004）2、《公路钢筋混凝土及预应力混凝土桥涵设计规范》（JTG D62-2004）3、《公路圬工桥涵设计规范》（JTG D61-2004）4、《公路桥涵地基与基础设计规范》（JTG D63-2007）5、《公路桥涵抗震设计细则》（JTG /TB02-01-2008）6、《公路工程抗震设计规范》（JTJ 004-89）7、《公路桥涵施工技术规范》（JTG/T F50 -20）8、《铁路混凝土结构耐久性设计规范》（TB1005-2010）二、工程概述本桥为跨越宁西线而设，桥址属清水河河谷，大部分为耕地，地势较平坦。
西南I线在此附近设(1-13+1-16+1-13)m板梁桥，桥面净宽5.5米，全宽6.5米，根据协议及现场情况，拆除既有桥，新建一座（1-16+3-20+1-16）m 空心板梁桥，跨越西南I线及西南II线，桥面净宽5.5米，桥梁全宽6.5米，本桥所处地区地震烈度：8度，公铁立交里程为（铁）DIyK39+575(右线)=（公）GKO+112.本桥位于直线上，跨线桥中心里程GK0+090，全桥长97.48米，桥梁按斜交20度设置。
三、主要技术标准1、设计荷载：公路II级；2、桥面布置：0.5米（防撞墙）+5.5米（行车道）+0.5米（防撞墙）=6.5米3、地震动峰值加速度：0.20g;反应谱特征周期0.35s;4、桥面横坡:2%双向人字坡；5、桥面纵坡：2.3%四、桥址地质概况根据现场调查及钻孔揭示工点范围主要有黏质黄土、细沙、粗砂、圆砾土及卵石土。
勘探期间地下水位高程约479.4米，水质对混凝土无侵蚀性。
特殊岩土：湿陷性黄土，根据试坑土工试验报告计算黄土层具有自重湿陷性，自重湿陷量为90.9mm,总湿陷量为312.5mm,湿陷土层厚度约12米，湿陷等级为II级。
