Piling Wharfs Stability Reliability Analysis Under The Action Research

High-pile wharf usually built in natural waters better conditions,but the steep slope shore, piling jobs on the Slope of Wharf widespread adverse effect on stability.Current,the Foundation Norm of Standing-Pile Wharf (JST147-1-2001) has not yet given pier piling the shore slope stability factor of safety and reliability of the specific formula, and the increasing popularity of applications on reliability,Therefore for bank slope gradient larger high pile wharf by pile driving under the influence of the security stability and reliability related research and evaluation is very important.Combining with the AnHui WuHu port a high pile wharf engineering related material, high-pile wharf slope and piling process has been simplified, and soil parameters randomly distributed through Monte-Carlo simulation calculation of the reliability index.The main contents include:(1) Steeper high-pile wharf by piling under the influence of the bank slope stability reliability as a research object, and summarizes the adverse impact piling high-pile wharf shore stabilization. Reviewed the wharf bank slope stability and reliability research.(2) Piling process of excess pore water pressure and vibration acceleration distribution and calculation methods,discussed the slope stability reliability of all kinds of analysis method,contrast chose the slope stability analysis method of simple resemble closely law established the bank slope stability function function, will the soil parameters of the random distribution using Monte-Carlo simulation method, for the calculation of reliability index, prepare the corresponding program.(3)Using the bank slope stability function function and calculation procedure in actual engineering, using the computer program for different pile number under the action of high pile wharf bank slope stability safety factor and reliability index.Using ABAQUS software pier bank slope stability safety factor in the case of pore water pressure has completely dissipated after piling, The results show that:significantly decreased compared to high-pile wharf the shore slope stability safety factor and reliability index piling process again piling soil consolidation, and decreases with the increase in the number of piling.
