EXPERIMENTAL STUDIES ON LABORATORY CBR OF NON-COHESIVE SOILS

Measuring Erodibility of Cohesive Soils Using Laboratory Submerged Jet Test

Shigella flexneri causes a severe form of bacillary dysentery characterized by cramping, diarrhea, and fever. S. flexneri uses a type three seceretion system (TTSS) to invade the colonic epithelium by injecting effector proteins directly into the host cell cytoplasm. The TTSS consists of a basal body, spanning both the outer and inner membranes, and a surface exposed needle. After the proper en...

Relation between swelling and erodibility of cohesive soils

Laboratory Studies of Air Stripping of VOC-Contaminated Soils

Bench-scale laboratory experiments were conducted to evaluate the effectiveness of air stripping for in situ remediation of benzene-contaminated soils. Several parametric studies were performed to evaluate the effect of soil grain size, air injection flow rate, and air inlet temperature on the benzene recovery efficiency. An increase in soil grain size produced a significant increase in benzene...

Title Pile Aging in Cohesive Soils

This technical note presents the results of a field investigation into pile aging in soft clay which was conducted over a period of ten years. Static load tests were conducted after the excess pore pressure generated by the installation of 6 m long driven concrete piles were fully equalised. These tests allowed the time-capacity aging profile to be established. A normalised capacity-time trend ...

Lateral Bearing Capacity of Piles in Cohesive Soils Based on Soils' Failure Strength Control

This paper presents the results of a series of numerical analysis carried out on piles in cohesive soils. Broms (1964a) proposed graphs to obtain ultimate lateral bearing capacity of such piles. However, the graphs do not cover all piles with different lengths. In this study, a finite difference program that is especially designed for piles is used. The investigations were carried out by varyin...
