Abstract
With substantial increase of industrialization, large quantities of toxic waste remain untreated, which is a serious geo-environmental issue. Pile foundation is being extensively used at many such sites to support weak soils, where the load transfer mechanism is either through skin friction, end bearing, or both. The present research paper focuses on influence of contamination on load–settlement characteristics of RCC model pile foundation for two different slenderness ratios (8 and 10) by carrying out experimental model test on both contaminated and non-contaminated soil subjected to various load inclinations (0°, 30°, 45° and 60°) from vertical axis. Various parameters analyzed and compared in this study are ultimate inclined bearing capacity, deflection, moment, soil resistance (p), engineering properties of soil, mineralogical content of soil and effect of lateral component on inclined bearing capacity. Various theories are used to estimate vertical and lateral capacity of the pile. P–Y curve is also constructed and used to calculate deflection, moment and soil resistance for the applied load. Experimental result of the model test is compared with the inclined capacity calculated using Meyerhof’s interaction equation. This investigation has revealed that contamination of soil leads to reduction in the bearing capacity. Also, there is a direct correlation established between increase in angle of load inclination with reduced bearing capacities, and increase in L/D ratio with increase in bearing capacities of pile.
