《江市区域供水二期工程及南通市沈海高速穿越工程顶管、水平定向钻技术研究》-毕业学术论文（设计）.doc

l l 摘要 地下管线是城市基础设施的重要组成部分，它包括给水、排水、燃气、热力、电信、电力、工业管道等几大类，就象人体内的“神经”和“血管”，日夜担负着传递信息和输送能量的工作，是城市赖以生存和发展的物质基础，是城市高效率高质量运转的保证，被誉为城市的“生命线”。随着全球经济的持续发展、人口的迅速增长以及城市化进程的不断加快，地下管线的需求正变得越来越大，而由于人们环保意识的增强和对生活质量的关注，在地下管线工程建设中传统的开挖埋设方法正带来日益严重的问题，在这种情况下，非开挖技术(TTTrencldess Technology)悄然兴起并得到飞速发展。顶管、水平定向钻技术更是广泛的应用到工程中。 目前我国经济正飞速发展，随着我国工程建设的快速发展，当前顶管、水平定向钻技术在我国有很广泛的应用，在很多工程建设方面取得了显著的成效。但是，顶管、水平定向钻施工时会对土体产生影响，使其承载力下降，会造成局部坍塌、沉降过大引发路堤变形、路面裂缝、冒浆等问题。 因此，本次毕业设计中，针对以上问题，对顶管、水平定向钻技术的施工原理与工艺，对地面造成的土体扰动、地层损失及工程影响进行了分析。结合工程实例，根据施工工艺及对工程的影响，研究与地层损失及地层隆沉相关的施工参数设计；并提出一些监测控制方法及质量控制标准。 关键词：顶管、水平定向钻技术、施工工艺、 地层损失、地层隆沉、参数设计、监测控制 Abstract Underground pipelines is an important part of urban infrastructures, which includes pipelines for water supply, drainage, gas, heat, telecommunications, electricity and industrial piping, just as the bodys nerve and vessel, charged with the work of passing information and distributing energy day and night. Underground pipelines, known as the citys lifeline, are the material base for citys survival and development and guarantee for citys high quality and efficient operation, With the continued development of the global economy, rapid population growth and accelerated urban-based process, the demand for underground pipeline is becoming larger. Due to the fact that people are becoming more environmental consciousness and care more about life quality, using traditional methods in the underground pipeline project construction is facing serious problems. Under this circumstance, trenchless technology (TTTrencldess Technology) has rise and develop rapidly. Pipe jacking, horizontal directional drilling technology has been widely applied to the projects. Chinas economy is developing rapidly as well as the construction works, pipe jacking, horizontal directional drilling technology can be applied to a wide range of projects in China. In many construction projects, trenchless technology has made remarkable achievements. However, pipe jacking, horizontal directional drilling co
