摘要
某大型工程桩基础在底板基坑的挖土施工中,一部分预应力高强混凝土工程管桩(PHC管桩)因桩间土的塌方而折断。本文对断桩原因和处理方案进行了研讨并用计算加以验证。
In the excavation of foundation pit in a large scaled construction, some prestressed high strength concrete tube piles fractured because of the inter pile soil slump. This article discusses the cause and the treatment with verification from calculation.
