山区地基中的岩面离地面较近,覆盖层不厚,因而工程中常采用变形小承载力高的基岩作为持力层。文章结合实际工程中墩基础的设计与应用,介绍了人工挖孔墩的设计计算方法,并对人工挖孔墩的竖向承载力取值、结构布置、构造要求等方面进行了论述,并提出一些探讨性意见,可供类似工程参考。 Rocky ground in mountainous area is close to the ground and the cover is not thick, therefore, the bedrock with high deformation and small bearing capacity is often used as the holding layer. Based on the design and application of pier foundation in practical engineering, this paper introduces the design and calculation method of artificial pier dig pier, discusses the value of vertical bearing capacity, structural arrangement and construction requirements of pier dig pier, and puts forward Some of the exploratory comments, for similar projects for reference.
