Abstract

The invention discloses a method for calculating the stability coefficient of a composite foundation filling slope based on a transfer coefficient method, which includes: step 1, for piles arranged in a square, the pile replacement rate can be obtained from the pile spacing s and the pile diameter d , the slope sliding mass is divided into several blocks; the divided blocks include those containing piles and those not containing piles; step 2, calculating the cross-sectional area A of the blocks not containing piles i and the cross-sectional area of ​​the bar with piles; step 3, calculate the soil bar gravity of the bar without piles and the soil bar gravity of the bar with piles; step 4, calculate the compound based on the calculation results of steps 2 and 3 Stability coefficient of foundation filling slope; solves the problem that the prior art regards piles and remaining soil in the reinforcement area as a kind of composite material in the stability evaluation of composite foundation slope, which does not conform to the actual situation of the project, so that the calculated composite foundation There are technical problems such as large errors in the stability coefficient of fill slopes.

Description

technical field

[0001] The invention belongs to the technical field of slope stability calculation, in particular to a method for calculating the stability coefficient of a composite foundation filling slope based on a transfer coefficient method. Background technique

[0002] When carrying out filling construction on soft soil foundations, composite foundations are often used to treat the soft soils to enhance the bearing capacity and anti-sliding stability of the foundations. Under the action of upper loads, the piles and soil can jointly bear the load through deformation coordination. , due to the large difference in the properties of the pile and the soil material, the upper load is not evenly distributed on the pile and the remaining soil. The influence of the pile-soil force ratio should be considered in the shear strength of the sliding surface of the slope; at present, in the stability evaluation of composite foundation slopes, the composite strength parameters of pi...
