实际工程中应根据场地的地质情况、施工难度、经济效益等方面综合考虑选用适合的方法解决抗浮问题。本工程人防地下结构中原定在基坑底部均匀布置20根抗拔桩，以满足抗浮设计要求。现因场地条件限制、施工难度、效率等问题，通过综合比较抗拔桩和抗拔锚杆的施工难度和工期，拟采用抗拔锚杆代替抗拔桩，并对方案进行可行性分析。

In real practice, suitable method to solve anti-floating problems is considered based on several parameters, such as field geological conditions, construction difficulties, economic benefits and so on. In order to meet the requirements of anti-floating design, the structure of the underground engineering of civil air defense was scheduled to set 20 uplift piles homogenously in the bottom of the foundation excavation. Due to the construction difficulty, efficiency and other issues, it intends to adopt uplift anchor instead of uplift piles, and a feasibility analysis of the plan has been conducted.
