Abstract:
In order to study the influence of mixing piles on base stability coefficient of composite soil nailing wall, based on the checking method of base stability coefficient of the common soil nailing wall, the checking formula of the composite soil nailing wall was added with the consideration of the shear capacity of mix piles. The calculation was conducted about the 14 projects mainly located in Shenzhen, Guangzhou and other areas. Three types of curve laws between the base stability coefficients of composite soil nailing walls and the length of mix piles were obtained. The analysis results show that it is obvious for the base stability coefficient increment of composite soil nailing walls, and it is suggested that the increment percent should not be more than 30% for mix piles in practice.
