紧固桩的承载力原理
摘要:介绍了紧固桩的施工设备与工艺;指出了对桩底土及桩周土的加密和桩的周围存在预应力是这种桩承载力提高的主要原因;两处的单桩承载力载荷试验的结果表明这种桩型具有广阔的应用前景。
Abstract:The construction equipment and technology of tight confined pile are introduced. It is pointed that the increase in bearing capacity of the pile results from the densification of the soil under point of pile and around pile shaft. The results of load test of pile in two sites have shown that the tight confined pile has great potential in engineering application.
