The present study investigates the effect of de-sanding (recycling system) on bearing capacity bored piles. Full-scale models were conducted two groups piles, first group was implemented without using this system, and second recycling system. All piles tested by static load test, considering time factor for which implemented. test results indicated a significant clear difference in when use sys...

The bearing capacity of CFA (Continuous Flight Auger) pile is not able to reach the design if proper construction performed due soil collapse at bottom pile. In this paper, three samples were prepared simulate pile: grouting sample; mixture and gravel; sand. failure surfaces each sample obtained by a uniaxial compression tests represented as three-dimensional point cloud laser scanning. Therefo...

Due to its faster implementation and potential cost savings for estimating the bearing capacity of PHC pipe piles, High Strain Dynamic Test (HSDT) offers an alternative approach Static Load (SLT). The report presents a study via those methods with sliding micrometer. And Pile Driving Analyzer (PDA) imported from United States is employed, determine design parameters pile foundation engineering ...

Currently, p-y models have been broadly adopted for estimating the lateral bearing capacity of large-diameter monopiles in offshore engineering. However, existing curves cannot reflect effect pile diameter D on response under local scouring conditions. In order to extend model a pile, well-calibrated three-dimensional pile-soil performed by ABAQUS is used study ultimate soil resistance P and in...

High-speed railways are built in deep soft-soil foundations interlayered with hard materials. However, the layers cannot be penetrated by conventional foundation treatment. Moreover, project cost is sometimes prohibitive, which an issue for post-construction subsidence control. The bag grouting pile a special grouting-pile-reinforcement technique treating This paper conducted tests on Ningbo-Ta...

A p-y curve method of pile near cohesionless soil slope under reversed lateral load is proposed. This takes into account the failure mode around and interaction between soil, derives ultimate resistance pile. Considering change original stress state due to deflection foundation, influence relative density, initial mean effective foundation on internal friction angle sand evaluated further accur...

Studies of the piles bearing capacity after strengthening soil by cement mortar pressure injection were carried out to determine pile foundations increasing patterns in a result soils cementation. Depending from volume and technological parameters, stress state around changes, additional pile-soil compression occurs friction along lateral surface increase, as well resistance under bottom end.
