This paper proposes the penetration displacement solutions of large-diameter open-ended steel pipe piles (LOSPs) with diameter exceeding 2 m subjected to hammering load. The ultimate forcing equilibrium relationships between LOSP and soil are analyzed, calculated formula for self-sinking depth is derived. Next, a partial differential equation pile by single blow in soft developed based on wave ...

In the field of PHC pile joints, it is important that prestressed high-strength concrete pipe piles are referred to as piles. conventional hoops, bamboo-like joints protrude from joint position at surface pile. Driving in, disturbing soil around pile, and affecting frictional resistance serious issues. To address such issues, herein, a new type clamping proposed. A method presented determine si...

The mechanical property of the pile-core–cement-soil interface is a crucial factor affecting shaft capacity expanded stiffened deep-cement-mixing (ESDCM) pile. research on characteristics steel-pipe–cement-soil very limited, and conventional concrete–cement-soil results cannot provide direct guidance for engineering application combination Hence, in this study, we employed model pile with combi...

The bearing capacity of a single pile in granular soil was analyzed piles under vertical loads in the study of the mechanism of shaft fiiction. The effect of the deformation modulus on the bearing capacity of the single pile in granular materials, and especially in sand, was examined. By using the FLAC program for the finite element analysis it was possible to predict quite accurately the load ...

In the article problem of geotechnical application clay nd claystone as a base driven pile foundations has been considered. When using these foundations, compaction zone is formed in space around pile. The purpose this research to analyze influence zones on results analytical and numerical calculations for predicting settlement layered soils. following tasks were solved: 1) existing investigati...
