Experimental Study on Vertical Compressive Static Load of Single Pile in Water Intake Pumping Station
Taking water intake pumping station as an example,the mechanical characteristics and settlement characteristics of hydraulic engineering foundation piles under vertical loads were studied.A single pile compressive static load test was carried out on a typical foundation pile,and the test device,loading method,and judgment method were defined.The characteristic value of the vertical compressive bearing capacity of a single pile was determined,and whether the test results met the design requirements was reviewed.It provides reference for the design and optimization of pile foundation of hydraulic engineering.The research results show that the characteristic value of vertical compressive capacity of single pile in this site is very reasonable and safe.The proportion of tip resistance of the selected 3 foundation piles in vertical bearing capacity is not high,showing a Q-s"slow change"curve,and the failure characteristic points are not obvious.
