Application and Analysis of Simplified Calculation Method for Multi-row Pile Support of a Certain Slope
摘要
Abstract
Multi-row pile support can effectively reinforce the slope,but there is still no perfect method for the calculation of multi-row piles in the project.In the case of one side slope,a simplified calculation method of"multi-row pile support+slope excavation in the pit"is proposed,the slope excavation is simplified to vertical excavation,and the vertical excavation depth is taken as 2/3 times the slope excavation depth,and the safety assessment of the original double-row pile support design scheme is carried out,and the results show that the stability safety factor of part of the slope section of the original support scheme does not meet the requirements of the specification,and the reinforcement scheme of adding two additional rows of piles in the middle of the original inner and outer row piles of part of the section is proposed,and the calculation and review of each row of piles are carried out through the simplified calculation method.The diagonal brace connection of the inner and outer row piles is considered as the support acting on the outer row piles,and for the inner row piles and the middle row piles,the retaining effect of the adjacent outer row piles is considered,and the vertical excavation part of the slope top is equivalent to the vertical load,and the results show that the reinforcement scheme can meet the requirements of the code.Through the comparison between the calculated deformation and the measured deformation of the original design scheme and the successful application of the reinforcement scheme,it is verified that the simplified calculation method has certain feasibility and engineering significance.关键词
