Numerical Analysis Of The Strut Frame Made Of Composed Soil-Nailing

The technique of strut frame made of composed soil nails comes from the combination of the developing technique of strut frame made of soil nails and other traditional method of strut frame. It is certificated in the engineering practice that this technique not only is economical easy to control and completed, such as the other methods of strut frame, but also break the applicability of common method of strut frame, which assure the wider applicability and foreground of the technique of strut frame made of composed soil nailsThis paper begins with the concept of the strut frame made of composed soil nails, analyzing the composition, engineering characters and job practice of the technique of strut frame made of composed soil nails. On the basis of the others, according to the constructional feature of the constitution of the composed soil nails, the computation mode of the he strut frame made of composed soil nails was set up to analyze the distortion of the he strut frame made of composed soil nails when it is stressed. With the engineering data, the strut frame made of composed soil nails is analyzed with the program ABABQUS, and the effects of the distortion characters, the property of the deposition of the ground, the mechanical property of the soil nails, the variation of the length and the separation of the soil nails, and the diametric of the mixing piles on the strut frame made of composed soil nails, and the distortion property of the strut frame made of composed soil nails under different ground conditions. On the analyze of the strut frame made of composed soil nails, suggestion on the design and construction of the strut frame made of composed soil nails is extracted.
