某深基坑工程雨后险情及处理

Analysis and treatment of dangerous status of a deep foundation pit after heavy rain

以某深基坑工程抢险加固处理为例,通过分析该基坑原设计方案及加固处理方案,从地质条件、设计、施工、周边环境等多方面深入分析发生险情的原因及抢险措施。在此论述的基础上提出了深基坑工程预防措施及对策。结果表明,基坑开挖前应通过详细的地质勘察,认真分析项目周边的排水条件,评估可能出现的风险,工程实施阶段应坚持动态设计信息化施工,随时监测结构的变形和环境变化情况,发现问题及时反馈解决。

Taking the rescue and reinforcement treatment of a deep foundation pit project as an example, through the analysis of the original design scheme and reinforcement treatment scheme of the foundation pit, the causes of the dangerous situation and the rescue measures are deeply analyzed from the geological conditions, design, construction, surrounding environment and other aspects. On the basis of this discussion, the preventive measures and Countermeasures for deep foundation pit engineering are put forward. The results show that: before the foundation pit excavation, the drainage conditions around the project shall be carefully analyzed through detailed geological investigation, and the possible risks shall be assessed. During the project implementation stage, the dynamic design and informatization construction shall be adhered to, the deformation of the structure and environmental changes shall be monitored at any time, and the problems found shall be fed back and solved in time.
