1、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
2、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ThesyntheticdesignofGroundfoundationandUndergroundstructureAbstractGeotechnicalengineeringisabroad-fieldsubjectwithcloselyintegratingtheoryandpractice,whichmainl
