建筑物采用复合地基是目前岩土工程界的热门话题,各类复合地基在工程界得到了广泛的应用。主要原因是充分利用地基土和土中的竖向加强体来共同承担荷载,这样就可以为建设单位节省大量建设资金。所谓桩、土共同作用如何达到是一项十分难解决的科题。目前市场上加强体份刚性和柔性两种,但材料组成却是多样化的。多样化的原因主要考虑桩、土如何达到共同作用的目的。本论文试图在这方面做出一点尝试。突出点为桩本身材料为砂、石子、水泥干性拌合料。主要考虑桩材料与新近填土压缩模量值差尽量缩小。以期达到桩、土共同的目的。另外场地填土回填时间较短,厚度较大,在有关文献中均没有记载。如何使回填土各向均匀,本文论述的方法也是较新的。目前,尚未发现有论文记载。同时,处理深度也是比较少见的。
The use of composite foundation in buildings is a hot topic in geotechnical engineering at present. Various types of composite foundations have been widely used in engineering. The main reason is to make full use of the vertical reinforcement in foundation soil and soil to share the load, thus saving a lot of construction funds for the construction unit. The so-called pile, soil how to achieve common effect is a very difficult subject. Currently on the market to enhance body rigidity and flexibility of two, but the material composition is diverse. The main reason for the diversification of the pile, soil, how to achieve the purpose of common ground. This thesis attempts to make some attempts in this respect. Prominent point for the pile itself is sand, gravel, cement dry mix. The main consideration is that the difference between the compressive modulus of the pile material and the newly-filled soil should be minimized. In order to achieve the pile, soil common purpose. In addition, the field fill backfill time is shorter and thicker, and there is no record in the relevant literature. How to make the backfill uniform, the method discussed in this article is relatively new. At present, no papers have been found. At the same time, the depth of treatment is relatively rare.
