Group Assessment Task $($Case Study Analysis$)-10\%$

Figure $1$ shows a hill slope road near Kampung Seringgus, near Bau, which collapsed due to heavy rain and inundated for two days. It is found that this was the second case within the month along the same road. As a design engineer for the consultant, you are appointed to redesign the hill slope road at the mentioned location. Figure $2$ illustrates the cross$-$section of the proposed new earth retaining wall design $($without drainage system$)$ for the rectification works of the slope failure. Evaluate the stability of the wall against rotation, translational failure and bearing capacity of soil subjected to the self$-$weight of the soil, retaining wall structure owns weight and possibility of water table development behind the retaining wall due to heavy rainfall. The stability assessment should be referring to local authority requirement i$.$e Jabatan Kerja Raya $($JKR$)$ and therefore, recommend workable slope remedial works options if the proposed design is failed.
