The foundation heave occurs in various patterns like doming, edge, cyclic, and lateral movement. Differential movement of expansive soil is more damaging than a uniform heave. It mostly affects lightly loaded structures like one or two-storey structures, highways, retaining walls, […]

It is stated that financial losses due to heaving in the United States are larger than those […]

In other words, preloading accelerates settlement of the soil before the construction of the structure. Commonly, the combination of preloading and vertical drains is used to make the method more effective. The function of […]

The process involves the application of vacuum pressure into a separated soil mass to decrease atmospheric pressure and pore water pressure, resulting in soil consolidation. The vacuum preloading technique was proposed by Kjellman in 1952 to […]

One can assess liquefaction potential through standard blasting tests, ground response analysis, laboratory tests, and expertise. The use of laboratory tests is not desirable due to difficulties in taking undisturbed samples and reconsolidation processes. […]
