简介:【摘要】伴随着城市化进程的不断加快,城市发展越来越严重地受到土地资源紧缺、水资源匮乏、交通拥堵、人口密度过高等城市综合征的制约。城市地下空间的开发是优化城市资源空间资源、实现城市用地内涵式发展、发掘城市用地开发潜力的重要途径。对于地下空间开发的深基坑工程,结构抗浮是必须考虑的问题。由于传统的基底抗浮工艺费时费力、资源耗费量大、公害污染严重的缺点,静水压力释放层技术随着建筑施工技术的提高和科技的进度,使该技术的应用打开了一个广阔的前景。特别是超大深基坑结构抗浮静水压力释放技术具有安全适用、技术先进、经济合理、确保工程质量、保护环境的优点。随着国家对环境保护越来越重视,静水压力技术符合海绵城市的设计理念,是地基基础设计和施工中绿色建筑工艺的代表。
