1、根据苏州市市政工程设计院有限责任公司设计的“吴中区中山路（灵天路~金枫路立交）改造工程”、投标文件及施工合同文件。

2、参考现行相关技术规范，工程建设标准强制性条文，苏州市工程建设管理部门颁发的有关质量、安全文明施工的规定及文件。

3、依据施工现场详细踏勘情况以及本公司类似工程的施工经验、技术力量和装备。

4、西北勘察设计院提供“苏州市吴中区中山路（灵天路~金枫路立交）改造工程岩土工程勘察报告。

中山路为木渎镇的交通性主干道，由于道路使用年数已达到设计年限，随着木渎经济的飞速发展，区域交通量的迅速增加，加上南环快速路西延开工建设后通过中山路的交通量迅速增加，中山路原有的双向四车道规模越来越不能满足不断增长的交通需求。另随着交通量的增长加重了道路的负担，虽经多次养护和维修，但道路部分路段还是产生龟裂、沉陷、坑凹等病害，影响到车辆的通行。道路迫切需要扩容，由双向四车道拓宽改造成双向六车道，以满足日益增长的交通量的需要。

中山路段现状道路路幅总宽40米，三幅式断面，标准横断面路幅分配为：5米人行道+4米非机动车道+2.5米机非分隔带+17米机动车道+2.5米机非分隔带+4米非机动车道+5米人行道。道路除交叉口外均为水泥混凝土路面，非机动车道均为沥青路面结构，现状路况很差。全线人行道及侧石现状破损严重。

改造后路幅总宽40米不变，双向四车道改建为双向六车道，具体为：4.5米人行道+4米非机动车道+机非隔离栅+10.5米机动车道+2米中央分隔带+10.5米机动车道+机非隔离栅+4米非机动车道+4.5米人行道。

机动车道及非机动车道横坡均为1.5%，由道路中心线向两侧排水；人行道横坡为1.5%，坡向道路中心。路拱均采用直线形式。路拱均采用直线形式。车行道边采用平侧石筑边，平石、侧石采用花岗岩材质。

新建桥梁因考虑到施工期间的交通疏导和管线搬迁，并且桥位处的地质条件较差，考虑到箱涵的结构整体性好，方便小节段施工，对管线搬迁的适应性好，所以新建下沙塘河桥采用8米跨径的箱涵，箱涵宽度为44米。

本项目包括道路工程[路面、路基、雨水、污水（沉井、顶管、倒虹管）、水泥搅拌桩、压密注浆]、桥梁工程。

1、道路等级、设计速度

独立基础工程施工方案1全线路基设计分一般路段、金山路以东北侧路段、桥头路段三种情况考虑。

行车道挖除老路路面结构至设计路槽底标高后（翻挖老路面结构0.606米），如老路基检测弯沉值＜220，压实度要求不低于93%，直接施工路面结构；如不满足要求，翻挖25cm，对原路基填土碾压整平后，现浇C20水泥砼板。
