CALCULATION OF STRUCTURE RETAINING WALLS OF LAND FOR HANDLING LANDSLIDES SEGMENT 1 VILLAGE ROAD MARGOMULYO KABUPATEN KUTAI KARTANEGARA

Abstract

Margomulyo Vilage area, District Loa Janan, a vilage located in the

District Loa Jana ,but in the vilage is an area that is prone to landslides, this is

due to topographical conditons in the area in the form of hily areas, mining and

agricultural region. Lack of suporting vegetation bufer zones rainwater and

make this area very prone to landslides in the event of rain, so at some point

along the river have sen the potential for erosion and landslide potential, which

requires extra care and handling of fast, responsive and acurate prior to the

ocurence of landslides as a whole in cros section of the riverbank.

Handling avalanches due to erosion of the river banks, of course, require

the existence of analysis and technical studie ,detailed and comprehensive, so it

can produce a design that is apropriate and efective in order to conform with

the original purpose of the handling of the avalanche can be achieved From the

calculation results can be concluded that ,dimensional wal pehanan high ground

is 3 meters and a width of 1 meter, 1 meter thick plate with a length of 10 meters

per segment review. Secure the stabilty of a retaining wal to bolster however

afect he shear, so that he necesary foundation piles with aditonal bracing to

the pile group to rigidify the structure of the wals and the pile.
