Bulging capacity of granular pile-anchors (Paperback)

Expansive soils are highly problematic soils with an innate capacity for swelling and shrinkage corresponding to changes in moisture regime. Because of the alternate swelling and shrinkage undergone by these soils in rainy seasons and summers, many lightly loaded civil engineering structures like residential buildings and pavements are severely cracked. It is, therefore, necessary to devise a suitable foundation for these soils. Granular pile- anchors (GPAs) are a recent foundation technique that proved quite effective in controlling the volumetric changes in expansive soils and also in improving the behaviour of expansive soils. In the design of GPAs, it is important to understand the uplift failure mode, which is basically bulging. This book on 'Bulging capacity of granular pile- anchors' discusses in detail the computation of bulging capacity of GPAs, which is nothing but the uplift failure load of GPAs. The book has considered various important parameters influencing the bulging capacity of a GPA and developed data which would be useful for both researchers and practising engineers working in the area of expansive soils.
