文档介绍：高速铁路地基加固技术
摘要我国地域辽阔,幅员广大,自然地理环境不同,土质各异,地基条件区域性较强。随着当前经济建设的蓬勃发展,有时不得不在地质条件不好的地方从事建设。因此,就需对天然软弱地基进行加固。高速铁路是20世纪交通运输领域的重大成果,是一个专业面极广,技术先进成熟的庞大系统工程,是人类的共同财富。而地基作为路基支承,绝不允许发生基底破坏,也不允许发生过大的工后沉降和沉降速率。对支承高速铁路路基的地基来说,除了强度要求外,还有变形条件和抗震要求。因此,高速铁路对地基要求相应较高。目前,国内外地基加固方法众多,很多方法还在不断发展和完善中。每一种处理方法都有它的适用范围和局限性,因而选用某一种地基加固方法时,一定要根据地基土质条件、工程要求、工期、造价、料源、施工机械设备条件等因素综合分析后确定。本设计综合国内外现行的各种地基加固方法,结合地下建筑工程,交通运输等个专业内容进行设计。通过查阅各种科技文献,参考专业资料,本设计对地基加固技术进行了专业,透彻的分析,系统的阐述了高速铁路地基加固技术的基本知识和基本原理。

Abstract China's vast territory and vast, geographical differences, different soil, the strong foundation of regional conditions. With the current vigorous development of economic construction, and sometimes had to geological conditions in poor areas in the building. Therefore, the need for natural weak foundation reinforcementHigh-speed railway transport in the 20th century the major achievements of the area, is a professional face a wide and advanced technology, mature huge project, is mon wealth of mankind. The foundation supported as a roadbed, in the basement must not be allowed to destroy, or allow too much in the post-settlement and settlement rate. Supporting high-speed railway roadbed on the ground, apart from the strength of demand, there are anti-seismic deformation conditions and requirements. Therefore, high-speed railway demands on higher groundAt present, domestic and foreign foundation strengthening many ways, are still many ways to continue to develop and improve in. Each approach has its scope and limitations, thus choose a certain kind of foundation strengthening methods, the foundation must be based on soil conditions, engineering requirements, Time, cost, source materials, construction machinery and equipment conditions and other prehensive analysis DeterminedThe integrated design of the various domestic and foreign foundation strengthening the existing method of underground construction, transportation, and other professional content design.
