The construction of inland river wharf is faced with the problems of excavation stability of harbor basin bank slope and its influence on the surrounding environment.On the basis of an inland river frame wharf under construction in Zhaoqing,GEO5 software is used to calculate the excavation stability of wharf bank slope.Taking safety factor,internal force of pile body and displacement of pile top as control indexes,the reinforcement scheme of bank slope is compared and analyzed.Considering the construction period,the dense row piles are finally used for reinforcement.On the basis of the field monitoring results,the reinforcement effect is evaluated by comparing the allowable values of the code.The results show that the reinforcement scheme of slope bottom cement mixing pile and slope waist cast-in-place pile can meet the requirements of the code after appropriate optimization.Before and after the completion of bank slope excavation,the maximum surface displacement and deep horizontal cumulative displacement are about 7 mm,less than the early warning value of 20 mm,and the slope top building inclination rate and change speed do not exceed the early warning value.The reinforcement of dense row piles effectively reduces the influence of bank slope excavation on the overall stability and slope top structures,and ensures the safety of bank slope and surrounding environment.It can provide reference for similar projects in the selection and analysis methods of reinforcement schemes.
