第一章、工程勘察方案

一、勘察目的及要求

详细勘察阶段，在初步勘察已有资料的基础上，应进一步查明沿线的工程地质、水文地质条件，从而为第1标段基础施工图设计提供依据。详勘阶段勘察目的及要求如下：

1、详细查明场地的地貌特征、地层、地质年代、岩性、成因类型、地质构造特征、水文地质条件。

2、详细查明沿线各层岩土的类别、分布、结构、厚度、坡度。查明岩土的物理力学性质，划分岩组和风化程度，确定地基承载力，提出基础类型及埋置深度等的意见，并对地基的稳定及承载能力作出评价。

3、详细查明线路方案的长大活动断裂，特别是全新世活动断裂的位置、产状、规模和破碎带宽度及其对工程的危害影响程度，并提出治理意见。

4、详细查明场地特殊土和不良地质现象（淤泥、淤泥质土、断裂、土洞、岩溶等）的特征和分布、性质和规模，分析评价特殊土和不良地质现象对工程的危害程度和影响，并提出防治措施及处理意见。

5、详细查明基岩的岩性、构造、岩面变化、风化程度，确定其坚硬程度、完整程度和基本质量等级，判定有无洞穴、破碎岩体或软弱岩层。

6、详细查明沿线河、湖淤积物的发育、分布，以及古建筑遗址、古河道等，并结合工程要求提出评价。

7、详细查明沿线范围的地表水水位、流量、历年最高水位、枯水位、水质等水文资料，以及补给、排泄条件与地下水的相互关系。

8、详细查明场地地下水的类型、性质、埋藏条件、补给排泄条件、变化幅度、地下水位、渗透性，判定地下水对混凝土及钢结构有无腐蚀性；查明孔隙承压水的水头高度及其地下水动态和周期变化规律，提出水质评价并确定施工图设计所需的水文地质参数。需要降水施工时，提出降水方法及有关计算参数，
