Arch-chord coupled anti-sliding structure is a new type of composed multiple single piles in specific form. The coupling effect pile and soil the most important key point. In this article, factors that affect bearing capacity load sharing ratio arch-chord are screened out, rule evaluation index affected by each factor analyzed. results show that, with increase diameter, value structural ultimat...

Pressure-grouted helical pile (PGHP) is an innovative piling system that allows a significant increase in capacity with relatively low additional cost. The constructed by applying pressurized grout during the installation of conventional piles. injected into ground through two nozzles welded to hollow shaft. This paper presents comprehensive laboratory study investigate effect three different n...

A vertical electro-osmosis method was proposed to improve the bearing capacity of piles in marine soft clay foundations. top-down test conducted by setting an anode and cathode at top bottom pile, respectively, while settings bottom-up were set opposite way. At same time, a pile without also up for comparison. The variation law water content, discharge volume, soil pressure, surface settlement ...

Determination of negative skin friction force and The neutral plan is one the challenges which face geotechnical engineers. Unfortunately, decreases bearing capacity pile because extra compressive on pile. In this research, a 3D FE models were used to investigate behavior single group in soft soil for surcharge load as embankment fill. And what are differences that will happen group. For fill l...

One of the constructions that can be used to overcome problem soft soil is through pile mattress bamboo construction. This construction consists arranged as mattresses and cluster piles. The several culms tied together (cluster pile). Cluster capabilities are not analysedfor strength result in wastage or failure. Hence, this study was intended analysethe ability clusters recorded direct observa...

This research presents the geotechnical zoning map of district 1 in Shiraz municipality with focus on allowable bearing capacity of foundation based on data from 160 boreholes. For this purpose, the mechanical properties are determined according to the results of direct shear, uniaxial, and SPT tests and then safe bearing capacity for strip foundations with widths of 1, 1.5, 2, and 2.5 m, and f...

In this paper, an analytical solution to the problem of interaction a pile-slab foundation with 2-layer elastic soil basement is proposed. A new method was proposed take into account nonlinearity soils in formulation. This consists limiting bearing capacity pile along lateral surface by strength adjacent and redistributing applied load toe. article, comparative analysis formulation numerical si...

To reasonably analyze the bearing characteristics of curved beam bridge pile foundation under combined action vertical force (V) and torque (T) in expansive soil, a method determining Tu (limit torque) V is proposed. Considering effects ground heave after immersion, load transfer function at pile–soil interface with positive negative friction resistance established. The nonlinear solution singl...
