(1)水文地质 路线所经区位于江苏省北部，在黄淮海平原南部。第四系覆盖厚度不大，土层薄，局部地段基岩裸露，属丘陵坚硬，半坚硬岩类工程地质区，地基承载力较大，岩石抗压强度700-1000kg/cm3。地下水受地质构造、断层的影响控制，分布不均，各地段差异很大，总的来说，基岩分布区地下水极少，断层以东沿运河及废黄河一带地下水较丰富，PH值为7-7.4，硬度为14-25度，单井出水量为40-90T/h，该地段为粉砂——壤土层，地下水位极易受气候、地表水的影响，平均地下水位0.8m，不够稳定。年平均气温15℃，极端最高气温38.3℃，极端最低气温-9.5℃，最大风速20.2m/s。

2.4路线设计总则:
(摘自<<公路路线设计规范>>)路线设计应在公路建设项目工程可行性研究报告所选定的路线走向与主要控制点的基础上,先作出总体设计,再结合主要技术指标的运用,进行路线方案对工程造价,自然环境,社会效益等有较大影响时,应做同等深度的多方案技术经济比较。

(1)路线设计应根据公路的等级及其在公路网中的作用,合理利用地形,正确运用标准.注意与铁路,航运，空运，管道运输等的配合,协作,并结合地形,地质,水文,筑路材料等自然条件,通过综合分析,认真进行方案研究,合理选用主要技术指标。 (2)路线设计对公路的平,纵,横三个方面应进行综合设计,做到平面顺适,纵坡均衡,横面合理。
高速公路,一级公路应特别注重线形设计,使之在视觉上能诱导视线,保持线形的连续性,在生理和心理上有安全感和舒适感。同时,还应同沿线环境相协调。 (3)路线与桥梁,隧道,立体交叉,沿线设施等构造物应组成有一定风格的建筑物群,并利用绿化或工程设施改善它们同沿线地形的配合,消除因修建公路而造成的对自然景观的破坏。高速公路,一级公路应借助公路透视或三维模型检查线形设计同沿线景观的配合与协调,其他各级公路有条件时,也可利用公路透视图检验线形设计。 (4)采用分期修建方案时，必须作出总体设计方案，并根据近，远期交通量以及资金筹措情况作出分期修建设计。分期修建的设计应使前期工程在后期仍能充分利用，并为后期工程的修建留有余地和创造有利条件。
3平面线形设计
3.1说明
根据近远期规划，建设规模和性质，现场勘测，确定路的基本走向和主要控制点。道路选线是一个涉及面广，影响因素多，设计性强的一项工作。它是由面到片，由片到线，由粗略到细致的过程，选线应注意的以下几点：
（1）道路选线应根据道路使用任务和性质，综合考虑路线区域，国民经济发展情况与远景规划。
(2)深入调查当地地形，气候，地质水文等情况。 (3)力求路线短捷及保证行车安全。
(4)选线要贯彻工程经济与运营经济结合的原则。 (5)充分利用地形，搞好路线平，纵横三面结合。
(6)大中桥位应在服从路线总方向的原则下，对路桥进行综合考虑。
(7)道路应尽量减少交叉次数，合理选用交叉类型，以达到行车安全畅通的目的。 (8)道路设计应实行远近结合，分期修建，分段定级的原则，以取得投资及用地
