| الملخص: | PLTU Parit Baru is located on the edge of the trench Kapuas River
where the topography conditionare slight slope and in the form of clay. The clay
soil depth is 30 m. The problem appears when the tidal river water for PLTU area
is flooded. Therefore, soil elevation should be increased and need construction of
slope protection. This study aims to determine what is the construction type of
slope protection for stability improving.
The construction of slope protection is choosen and adjusted with the
condition of soil where the bearing capacity and shear strength are low. In this
study, rip-rap with thickness of 0,3 m is choosen to set up in the surface of 2H: 1V
slope and 4 m wooden pile is combinated under the rip-rap. The construction
design was done by manual and the result was simulated with Plaxis software.
The result of design shows that use of wooden pile construction under the
rip-rap with space 0,5 m between the pile can supports the load of rip-rap rocks.
The analysis of slope stability with slope/W show that construction of slope
protection using rip rap has safety factor (SF)= 0,664 and the construction of
slope protection using rip-rap and wooden pile has safety factor (SF)= 1,604. The
result of manual calculation shows 36,561 cm for construction settlement. Global
analysis is done by Plaxis program. The output of plaxis shows that the
construction is safe to static load (SF= 1,202), to earthquake load (SF= 1,201),
and 0,25 m for total displacement of constructions The acceleration of earthquake
for Plaxis input is adpted with Indonesia Earthquake Map Zone 2012 of 0,05g |
