Design of Gabion Walls

Gabion walls are made up of row upon row of orthogonal cages or baskets (gabions) which are filled with rock fragments/cobbles and tied together....

New Insights on the Failure of Fukae Bridge (Kobe 1995)

Researchers from the Department of Civil, Environmental, and Geomatic Engineering, ETH Zurich, Switzerland have offered new insights on the failure of Fukae Bridge during...

Negative Skin Friction on Pile Foundation

Negative skin friction is a downward drag force exerted on a pile by the soil surrounding it. This is the reverse of the normal...

Normally Consolidated and Overconsolidated Soils

When a saturated clay is subjected to external pressure, the pressure is initially taken up by the water in the pores thereby leading to...

Application of Effective Stress Concept in the Analysis of Cohesive Soils

The application of load on a saturated soil increases the pore water pressure. This sets up a hydraulic gradient which causes the water to...

Evaluation of Surcharge Pressure of Pad Foundations on Retaining Walls

Surcharge pressure on earth retaining walls can arise from different sources such as loads from adjacent buildings, fills, roadways and traffic actions, construction activities,...

Sheet Pile Walls and their Uses

Sheet pile walls are thin retaining walls constructed to retain earth, water, or any other fill material. They are typically thinner than masonry or...

Effects of Diesel Contamination on the Engineering Properties of Natural Soils

Soil contamination is a serious problem and major environmental problem worldwide. Oil contamination of soils can occur as a result of oil drilling and...

Recommended Depth of Exploration for Site Investigation

Soil is a complex and highly variable product of nature, and the extent of this variation is known in advance. As a result, site...

Plates on Elastic Foundation

Many problems of practical importance can be related to the solution of plates resting on an elastic foundation. Reinforced concrete pavements of highways and...

Modulus of Subgrade Reaction of Soils

The modulus of subgrade reaction ks (also called the coefficient of subgrade reaction of soil) is the ratio between the pressure against a flat...

Difference Between Pile Load Test and Pile Integrity Test

Pile foundations are slender structures used to transmit superstructure load to firmer sub-soil stratum beneath the natural ground surface. They can also be used...
