The affected area comprises thick section of highly weathered friable sandstone. Cutting of slope for road construction destabilized the slope, infiltration of water due to continuous or heavy downpour led to oversaturation and reduction of shearing stre

This road section, specifically, KepreΓÇôTongikroΓÇôMongjang has high concentration of slope cut failures.
Kepre Tongikro Mongjang slide No.3
Kepre Tongikro Mongjang road section.
1. Construction and timely maintenance of lined hillside draiNGe system.
2. Construction of retaining wall with sufficient weep holes founded on sound substratum may be considered.

1. Removal of toe support during road construction.
2. Weak slope forming material:  highly weathered friable sandstone
3. Development of local hydrostatic pore pressure due to incessant rainfall rendering the weak slope to lose its shear strength.
