Abstract


High pile pier piling construction often slope stability without significant adverse effects , the construction phase of the marina slope stability has become a port engineering design and construction of an extremely worthy of concern. Currently Port Engineering Foundation specification (JTJ250-98) in the slope and foundation stability calculations have not given pier piling Bank Stability specific formula to engineering design great inconvenience , it is necessary to carry out piling role Pier slope stability studies to meet the design requirements. This paper studies the piling construction generated excess pore water pressure , vibration, acceleration , piling speed and other factors on the slope stability of the adverse effects of the use of cylindrical cavity expansion theory analysis of the pile after pile soil stress distribution and excess pore water pressure distribution law , analysis of the piling soil body vibration acceleration attenuation law and on the slope stability. In the circular slip based on the theory deduced piling under slope stability safety factor is calculated , and the preparation of the corresponding computer program for practical engineering piling slope stability calculations provide a theoretical basis and calculation methods. Combined with specific project examples , calculate and analyze the piling of a pier slope stability degree of influence , the calculation results with the engineering practice more consistent and, finally, the piling caused landslide prevention and remediation measures .
