Whether the inhomogeneity of mudstone foundation leads to abnormal bearing capacity driven pile remains controversial. This study introduces standard penetration test hammering number and needle strength for quantitative analysis by macroscopic observation engineering field on stratum self-structure microscopic simple feasible electronic magnification. The typical examples demonstrated that pil...

Multi-belled piles are with enlarged ends; these have one or further bells at the lower third part of pile. These suitable for many soils problems such as softening clay, variation groundwater table, expansive soils, black cotton soil, and loose sand. The current study reviewed behavior belled in multi-layer subjected to axial compression pullout loading. review covered experimental theoretical...

The design of large open steel piles driven at chalk sites suffers from considerable uncertainty, leading to major difficulties in many significant onshore and offshore projects. This paper describes recent instrumented driving, monotonic testing failure, restrike tests conducted on primarily low- medium-density a site North-western France. experiments are described interpreted with reference h...

ABSTRACT: The problem of lateral load induced on piles under earthquake has been plaguing professional engineers, geo-technical investigators and researchers alike for quite some time. The normal practice is to ensure that the fixed base shear of column does not exceed the static shear load capacity of piles. The inertial and stiffness effect of pile is usually ignored in dynamic earthquake ana...

In the common practice of geotechnical design, state soil is considered fully saturated, while recent examples show importance consideration unsaturated conditions as well due to location groundwater table at deeper levels. However, it problematic design a foundation and calculate bearing capacity internal stress in needs be quantified. The mechanics soils are critical engineering, especially w...
