水泥攪拌樁復(fù)合土釘支護(hù)技術(shù)的應(yīng)用與研究
[Abstract]:Due to the rapid economic growth in recent years, the real estate industry has also been rapid development, high-rise buildings have sprung up, the aboveground space has become increasingly scarce, the use of underground space has been a trend. However, the use of underground space will have to face a problem-foundation pit support. Soil nailing is widely used because of its simplicity, rapidity and economy. However, soil nailing support also has some shortcomings, it is not suitable for use in soft soil areas, and when the surrounding environment is more complicated and the deformation requirements are more strict, so the application of this support technology is limited to a large extent. Composite soil nailing is produced under this background. Composite soil nailing support is based on the development of pure soil nailing support, it uses the advantages of other support to make up for the shortcomings of simple soil nailing support, while retaining many advantages of soil nailing support. But the composite soil nailing support started late, its action mechanism is not clear, the theoretical basis is not enough, more rely on experience. In order to understand the composite soil nailing, this technique is widely used. This paper takes the composite soil nailing support of cement mixing pile as an object, and uses abaqus finite element software to simulate and analyze it. The purpose of this paper is to discuss the action mechanism of composite soil nailing and to summarize the law of deformation and internal force of composite soil nailing support. At the same time, the optimum design of soil nailing parameters and the optimum thickness of mixing pile and the optimum depth of mixing pile into the bottom of the pit are given. The main work and innovations of this paper are as follows: (1) the advantages of soil nailing support are expounded and the shortcomings of soil nailing support are pointed out. Because the theoretical research of composite soil nailing is relatively backward and the mechanism of action is not very clear, it is pointed out that the paper will take the composite soil nailing support of mixing pile as the object. Further research on composite soil nailing support is carried out. (2) several composite soil nailing technologies of mixing piles are listed and applied in concrete projects. It is pointed out that the advantages of composite soil nailing support of mixing pile are obvious under which conditions. (3) several aspects of checking calculation of stability of composite soil nailing support of mixing pile are discussed. (4) based on abaqus finite element software, an ideal model is hypothesized and simulated numerically. The horizontal displacement, ground subsidence, bottom uplift and internal force variation of soil nailing and mixing pile are obtained. The parameters of soil nailing are optimized, and the optimum thickness and depth of mixing pile are discussed. (5) combined with a concrete engineering example, the finite element software is used to simulate the soil nailing again, and the monitoring data are combined with the actual monitoring data. By comparing and analyzing the three results, it is pointed out that the law of partial deformation and internal force of mixed pile composite soil nailing structure is reasonable to a certain extent, and the selection of various parameters of supporting structure in the example is evaluated. Provides some reference information for design.
