-18- <br />• <br />The_cut No._7 is a long and high cut excavated in colluvial <br />soils. Its height reaches probably more than 60 feet at several <br />locations. The average cut slope is between 50 to 60 degrees. <br />At several locations, significant sloughing can be observed. <br />As a result of sloughing, the cut portions above the sloughs <br />are undercut and they are at a vertical slope. It can be expected <br />that sloughing will continue in the future. Compared to other <br />cuts along the gravel road, this road cut shows numerous sloughing <br />problems. <br />The_last_road_cut,_No._8, is again excavated in colluvial <br />-- --- --- --- --- - <br />soils. Its maximum height reaches some 55 feet; the cut has <br />been excavated at a slope of approximately 45 to 55 degrees. <br />Extensive sloughing can be observed along all the cut length. <br />Because of sloughing, the upper cut portions are steeper, up <br />to vertical; the lower cut portions are flatter, <br />Basic data on individual cuts as discussed in this chapter <br />are tabulated in Table 1, Existing Road Cuts Parameters.
