“…When subjected to a 60 kN force, the treated marine clay deviates by 81.82 percent in terms of displacement. Using data from [3], the percentage of displacement that is different when 10 kN of load is imposed on the foundation after the treatment of marine clay by using PU foam is 90% in the same parameter of marine clay properties. This shows that lime column can also be used to cure coastal clay.…”

The coastal area is one of the environmentally vulnerable areas, with soil characteristics such as weak soil and marine clay, which is classified as hazardous soft soil. Because marine clay has poor mechanical and physical properties, foundation conditions such as pad footing were unstable and prone to corruption. As a result, the lime column will be used to stabilize marine clay in this study. The purpose of this research is to investigate the deformation of marine clay with lime to increase shear strength and reduce excessive settlement by analyzing data from previous studies and conducting a review of the literature, as well as to investigate the deformation of untreated and treated marine clay with lime columns and PLAXIS software projection. Compared to the traditional method, PLAXIS 2D software is one of the most cost-effective ways to test a foundation, such as the pad footing. At the same time, PLAXIS 2D was able to shorten the time required to achieve an analytical result. The results of the settlement and stress value have been taken after the computation and analysis from PLAXIS 2D. The greatest percentage difference between untreated and treated marine clay for stress and displacement is 81.82 percent and 7.98 percent, respectively.

“…Lightweight polyurethane (PU) foam is an effective ground improvement technique for addressing differential soil foundation settling, primarily for infrastructure such as roads, highways, and parking lots. The goal of the research is to investigate how soil uplift and settling interact using the technique of finite elements, overburden load change, and PU foam thickness [8].…”

Polyurethane foam (P.U.) injection resin techniques have been widely used for slab crack repair, soil improvement, and structural crack repair over the past 20 years. In this study, numerical investigations were carried out to enhance the strength of both sand and clay soils via utilizing polyurethane foam as inclusion material. The investigation was conducted using ‘GeoStudio (SLOPE/W) 2D’ software to model 6 m high homogeneous slopes made of soft clay and medium sand with varying slope angles (25°, 30°, 35°) on same soil extended up to 9 m depth and with inclusion of polyurethane foam piles of varying diameter (0.5 m, 0.8 m), length (up to 10 m) and spacing (0.5 m, 1 m, 2 m) in the slope face. The numerical model was verified using experimental test results conducted by Hassona and Abdelnaeem (Physical and mechanical properties of polyurethane foam conditioned sand. MSc, Civil Engineering Department, Faculty of Engineering Minia University). The results revealed that, for slope angle, Ø = 30°, the factor of safety for clay soil increased when using polyurethane piles (diameter, 0.5 m and 10 m length) having spacing of two m, one m, half m, and when used as sheet piles, respectively. The factor of safety for clay soil increased significantly when using polyurethane piles (diameter, 0.8 m, and 10 m length) having spacing the same as before and as sheet piles having width of 0.5 and 0.8 m, respectively. Also, for medium dense sand soil, using polyurethane piles (diameter, 0.5 m and 10 m length) having spacing the same as before, and as sheet piles increased factor of safety much more than that for clay soil. In addition, for medium dense sand soil similar observation were noticed using polyurethane piles (diameter 0.8 m, and 10 m length) having spacing the same as before, and as sheet piles, respectively. In addition, the effects of slope angles also studied.
