Study on Building Settlement Problems & its Remedial Measures

In recent years, high buildings have emerged in large numbers rapidly. Due to the increase of floor and load, building body may produce settlement unevenly. Severe settlement may endanger the safety of building. Therefore, it is of great importance to monitor building in real time. Foundations are key element in construction projects. Identification of foundation failures and providing necessary treatment is very important. Many foundation failures are due to inadequate protection to foundation soils, improper geotechnical investigation and design error, improper sequence of construction and water level fluctuation. Differential settlement between foundations’ elements induces additional stresses in the structural elements. In general, the amount of settlement that a structure can undergo without distress is large, provided that the structure settles uniformly. However, based on the fact that the soil under the foundation may not be uniform in nature and the loads transferred from the superstructure to the foundation are variable, differential settlements between the foundation elements are expected. This works on different causes for distress of foundation and also discusses their solutions to overcome and prevent these failures in consideration. The questionnaire survey was conducted to rate the factors that contribute to the problem/defects of foundation construction and remedial approach for foundation failure.
