Pit bottom anti-upheaval stability analysis method and device suitable for narrow foundation pit
The invention discloses a pit bottom anti-upheaval stability analysis method and device suitable for a narrow foundation pit, and relates to the technical field of geotechnical engineering.The pit bottom anti-upheaval stability analysis method suitable for the narrow foundation pit is suitable for anchoring type and supporting type narrow foundation pits and comprises the following steps that whether a current foundation pit is the narrow foundation pit or not is judged; when the current foundation pit is a narrow foundation pit, a soil body is divided into strip blocks based on the principle of a Sweden strip division method; and carrying out stress analysis on the divided strip blocks, and calculating a pit bottom anti-upheaval stability safety coefficient. The supporting and retaining structure can be prevented from being embedded too deep, and better social benefits and economic benefits are achieved.
本发明公开了一种适用于窄基坑的坑底抗隆起稳定性分析方法和装置，涉及岩土工程技术领域，其中，适用于窄基坑的坑底抗隆起稳定性分析方法，适用于锚拉式和支撑式窄基坑，包括以下步骤：判断当前基坑是否为窄基坑；在当前基坑为窄基坑时，基于瑞典条分法原理，将土体划分为条块；对划分的条块进行受力分析，计算坑底抗隆起稳定性安全系数。本发明可避免支挡结构嵌固过深，具备更好的社会效益和经济效益。
