详细工程地质勘察大纲
一、工程概况 1.1 工程简介
京台高速公路廊坊段是国家高速公路网中北京—台北高速公路 的组成部分,起自北京市安定镇东南的京冀省界,与北京规划的北京 至济南高速公路相接,过廊坊市广阳区、永清县、安次区,止于天津 市石各庄西南的冀津省界,与天津市在建的 G112 线高速公路相接。 路线大致为南北—东西走向。延伸范围地理坐标大致为东经 116°30′~117°00′,北纬 39°30′~39°00′。
最终确定公路路线和构造物的布设位置。 2) 查明构造物地基的地质结构、工程地质及水文地质条件,准
确提供工程和基础设计、施工必需的地质参数。 3) 根据初勘拟定的对不良地质、特殊岩土防治的方案,具体查
明其分布范围、性质,提供防治设计必需的地质资料和地质 参数。 4) 对沿线筑路材料料场进行复核和补充勘察,最后确定施工 时所采用的料场。
