某深基坑支护方案优化设计

Optimized Design on Support Scheme for A Deep Foundation Pit

结合某深基坑工程实例,对比分析了深基坑常用支护结构的特点,确定并设计了该深基坑的支护方案。基于安全可靠、经济合理、施工便利和保证工期的设计原则将深基坑分为北侧、南侧和东西侧三段进行设计。结果表明:既保证了基坑的安全可靠又利用现有场地尽可能地降低了工程造价。

Combined with the case of certain deep foundation pit, the support scheme thereof is confirmed and designed depending on the comparison and analysis of the characteristics of such structures common used. Based on the principle of safety, reliability, economical rationality, convenient construction and period to be guaranteed, the deep foundation pit is designed by north, south, east-west sections. The result shows that the design not only guarantees the safety and reliability of the foundation pit, but also cut down the project cost as low as possible in virtue of the existing space.
