The effect of skirt footings for road settlement on peat soil

Abstract

Abstract The construction of peat soils is a big challenge in the construction world coupled with the very special nature of peat soil. Road construction on peat soil is a major obstacle because the deformation that occurs on the road is so large. Skirt footings are one of the shallow foundations commonly used for building offshore oil refineries. With the principle of making soil that has a low bearing capacity into a single unit to be able to withstand the burden on it. Skirt footings are placed under the embankment with a parallel position stretching to the width of the road plan. Among the skirt, footings are connected with steel straps so that during the loading process the skirt footings decrease can be controlled. The purpose of this research is to make skirt footings a shallow foundation under a road built on peat soil. Tests were also carried out on two models of shallow foundation to determine the effect produced by skirt footings on the soil. The other two types of shallow foundation models are un-skirted footings and mini piles. Comparison of the results of tests between skirt footings with un-skirted footings, it can be concluded that skirts under circular footings act as a buffer against the effective stress of the soil. While from the comparison of test results between skirt footings with mini piles, it can be concluded that circular footings play a role in reducing the effect of the differential settlement on the soil. The results of this study are that skirt footing can withstand differential settlement patterns and able to increase road stability.
