The Calculation Analysis of Supporting Structure with No-Load CFG Composite Foundation

This paper introduces the design selection and implementation program of the supporting structure of no-load side-direction excavated CFG composite foundation, in the case of the foundation pit excavation of stage bin of the Jinan Cultural Arts Center Grand Theater. The monitoring data shows that the lateral reinforcement effect of no-load CFG composite foundation can not be discounted. Based on composite foundation and rock mechanics, consider the no-load CFG composite foundation as the composite soil, build its mechanics index system and calculation method. Calculating and analyzing of the supporting structure that placing a row of anchor cable in cantilever double-row pile and double-row pile by means of applying composite soil parameters and using the pit design software and numerical simulation, and comparing the result with actual monitoring data. Therefore, we can further prove that lateral reinforcement effect on soils by considering CFG composite foundation.
