按苏联1955年天然地基设计规范(HиTY127-55)所推荐的方法计算基础的沉降时,计算过程十分冗繁,所以最近国内外一些工程技术杂志上先后发表了几篇有关简化这个方法的文章。不过对于地基压缩层厚度的确定,在一般地基条件下(如在压缩层范围内土的容重不等)都没有给出精确迅速实用的计算方法,尚需经过多次试算,方能求得。 本文根据H(?)TY127-55所建议的压缩层厚度的条件p_z=0.2p(δz) (1)导出一式,据以制出了曲线图,用此曲线图可以很方便地求出任何地基条件下的压缩层厚度。这样,对计算基础的沉降可得到进一步
When calculating settlements based on the Soviet Union’s 1955 Natural Foundation Design Code (Hyty 127-55), the calculation process was very tedious. Therefore, several engineering and technology magazines at home and abroad have published several articles on simplifying this method. However, for the determination of the thickness of the compression layer of the foundation, no accurate and practical calculation method is given under general foundation conditions (such as the unconformable bulk density of the soil within the compression layer). It is still necessary to go through many trial calculations to obtain . This paper derives a formula based on the condition of the compressive layer thickness p_z=0.2p(δz) (1) suggested by H(?)TY127-55. Based on this, a graph is drawn. Using this graph, one can easily find any foundation. Compressed layer thickness under conditions. In this way, the settlement of the calculation basis can be further
