Preloading Model on Soft Soil with Inclusion Thermal Induction Vertical and Incline Types

Soft clay has a relatively low subgrade bearing capacity. The aim is to obtain physical values, mineralogy, mechanical strength values, values for reduction. The research method used is preloading in a test tube measuring ۵۰í—۷۰í—۱۵۰ cm. Each cycle of preloading and thermal induction used a fixed load of ۰.۰۱۵ kg/cm². Thermal induction is given vertically and obliquely with temperature variations of ۱۰۰, ۲۰۰, ۳۰۰, and ۴۰۰ °C. The main observation point is a distance of ۱۵ cm from the center of the induction. At ۴۰۰ °C inclined induction, the water content is ۱۷.۳۶% (from the initial water content of ۵۹.۰۷%), the soil cohesion is ۲۱.۷۵. kN/m², the value of unconfined compressive strength is ۶۷.۷۲ kN/m², the highest modulus of elasticity is ۴۵۹۳ kN/m۲, and the decrease is ۵.۱۳ cm. XRD, SEM, EDS results before heating showed mineralogy ۰ (۶۵.۰۶%), Ca (۱۳.۳۰%), Na (۳.۶۴%), Mg (۲.۱۵%), Al (۶.۶۳%), Si (۸.۵۲%), Sn (۰.۷۰%) and did not change significantly after heating at ۴۰۰ °C. The results after heating included ۰ (۵۸.۳۹%), Ca (۱۴.۰۹%), Na (۰.۷۲%), Mg (۱.۱۶%), Al (۶.۶۳%), Si (۱۴.۷۲%), Sn (۲.۵۴%). The novelty obtained is to change very soft conditions became medium conditions. Doi: ۱۰.۲۸۹۹۱/cej-۲۰۲۱-۰۳۰۹۱۷۰۵ Full Text: PDFSoft clay has a relatively low subgrade bearing capacity.
