《武广客运专线衡阳站岩土工程详细地质勘察》》-毕业论文.doc

PAGE PAGE 1 摘 要 近年来，随着国民经济的高速发展，中国的铁路建设也进入了一个前所未有的时代。2008年4月18日，我国自主知识产权的和谐号动车下线，开创了我国高速铁路的新时代，继而京津高铁的建成通车拉开了我国高速铁路建设的序幕。京沪高铁、郑西高铁的投入建设标志着我国高速铁路建设高峰期的到来。火车速度一次比一次高，当然对铁路建设的要求也就会越来越高和越来越严格，并且建设的地质环境也越来越复杂。因此，这对铁路工程地质勘查的理论和技术方法的要求也越来越高。以便于为铁路建设提供更加准确可靠的地质依据。 铁路工程地质勘察是铁路建设中最基本也是最重要的一个环节，是铁路建设的基础性工作。它的主要任务是查明铁路沿线的工程地质条件、不良工程地质问题并进行分析和评价。为铁路建设提供可靠的、准确的、完整的勘察资料和地质依据，并且要考虑到环境地质问题，以确保铁路建设的安全稳定、经济合理。 本文主要是关于武广客运专线衡阳站岩土工程详细地质勘察。为了能够提供可靠准确的地质资料，本次勘察采用了多种勘察方法和手段。包括全取芯钻探、现场标贯试验、动、静力触探试验、波速测试、注水试验等。对采集的资料进行综合的分析与整理，为铁路建设部门提供相关的推荐值。本文还对衡阳站建设场地的水文地质条件、不良工程地质问题进行了分析与评价，并给出了处理意见。对于地基和桩基也结合材料给了建议，供有关部门设计参考。此工程预算造价为2635766元。 关键词：工程地质勘察；标准贯入试验；液化；地基 Abstract In recent years, with the rapid development of the national economy, Chinas railway construction has entered an unprecedented age. on April 18, 2008, our country proprietary intellectual property right’s train the harm nation moving which founded our country high-speed railroads new times. Then Beijing and Tianjin high-speed railroad has build and revolving. This opens to the traffic and raises the curtain for high-speed railway construction of our country. while Beijing-Shanghai high-speed railway and Zhengzhou-Xian high speed railway building which symbolizes our country high-speed railroad construction peak arrival. The train’s speed one time compared to high, And the requirements of the railway construction will also more and more high and more and more strict, and the construction’s environment becomes more and more complex. Therefore, the geological survey’s requirements of the railway works in theory and technique are more and more high, In order to provide a more accurate and reliable geological basis for Railway construction. Railway engineering geological reconnaissance of the railway construction is the most basic and most important aspect. Also is the foundation of the railway construction work. Its primary mission is verifies engineering geology condition the bad engineering geology question and analysis and eval
