H型预应力混凝土护岸桩室内模型试验研究
Experimental Study on Indoor Model of H-typed Prestressed Concrete Bank Protection Pile
摘要
Abstract
In order to explore the distribution of soil pressure on the side of the pile,bending moment of pile shaft and horizontal displacement of the pile top during the excavation and pile loading stages of the H-shaped prestressed concrete piles,three groups of indoor scaled model tests with prestressed rectangular piles and with or without prestressed H-shaped piles are carried out.And the test results show that the lateral earth pressure on both sides of the sheet pile has the same trend as the static earth pressure calcula-tion value when it is not excavated,but the measured earth pressure at different depths is always lower than the static earth pressure calculation value.In the excavation stage,the lateral earth pressure on the excavation side of prestressed H-shaped piles is smaller than that of rectangular sheet piles and non-pres-tressed H-shaped piles.The ultimate bearing capacity of H-shaped piles under prestressed condition is a-bout 1.33 times of that of rectangular sheet piles,taking the stacking weight at the critical displacement value as the bearing capacity index.The results show that the prestressed H-type piles have the optimal comprehensive performance,which can effectively improve the mechanical behavior of the pile shaft and significantly enhance the bearing capacity,thus possessing great engineering application value.关键词
