地基基础及地下结构综合设计 摘 要 岩土工程是一门专业领域广、理论与实践紧密结合的学科，主要包括边坡与基坑支护、隧道及地下建筑工程、地基处理、基础工程等内容，其以土力学和岩体力学为基本课程，基础工程、地基处理、边坡与基坑支护、地下结构设计原理与方法等为专业课程。最近几十年，随着国内外高层建筑、高速公路、隧道等的蓬勃发展，岩土工程获得了丰富的实践经验和理论成果。 本地基基础及地下结构综合设计共包含四部分，分别为住宅小区基坑支护设计、某商住楼基础设计、某二级公路软土路堤路基加固设计和姜源岭隧道设计，其中基坑支护采用土钉墙支护、高层建筑采用箱形基础、软土路基分别采用堆载排水固结法和水泥土搅拌桩复合地基法设计并选择合理方案，隧道主要针对深埋埋V级围岩采用喷锚和钢架复合支护。由于时间有限，各设计中主要以结构设计为主，施工组织概预算与质量监测等内容为辅。 关键词：土钉墙，箱形基础，堆载预压法，V级围岩复合支护 The synthetic design of Ground foundation and Underground structure Abstract Geotechnical engineering is a broad-field subject with closely integrating theory and practice, which mainly including pit slope protection, tunnel, ground treatment, foundation engineering, etc. It takes soil mechanics and rock mechanics as the basic curriculum, and foundation engineering, ground treatment, hole excavated for building foundation and side slope supports and protections, the underground structural design principle and the method, the tunneling and so on are the special course. In recent decades, along with the domestic and foreign high-rise constructions, the highway and the tunnel’s vigorous development, the geotechnical engineering has obtained much rich experience and theory achievement. This synthetic design contains four parts, Foundation Pit Support design of a residential community, high-level box shape foundation design , a second - class road of soft soil roadbed reinforcement design and JiangYuanLing tunnel design. The foundation pit support design of a residential community uses soil nail wall, the soft soil roadbed uses prefabricated drains and the cemented soil mixed pile composite foundation as basic operations designs and chooses the reasonable one, high - rise building uses box shape foundation design, the tunnel mainly aims at the V level of adjacent rock to use spurts the anchor and the steel frame compound supports and protections,. As the time is limited, every single design mainly takes structural design primarily, and construction organization, budget e
