Abstract
ANALISYS OF VARIOUS OF SAFETY FACTORS OF SUBGRADE REACTION OF SINGLE CONCRETE PIPE POLES NAILED-SLAB SYSYTEM ON SOFT CLAY OKTA RESTU PUTRI 133110088 Abstract The Nailed-slab Pavement System is interaction of plate-pole-soil makes the plate more stiff, a pole mounted under the plate function as plate stiffener so that the load can be spread more broadly to soft clay, so expect pavement gives a good ability and aovoid from differential settlement due to the burden across the pavement, Nailed-slab system was not method of soils repairment but one of alternative methode to incraese the performance of pavement on the soft clay. The research did to know effect of safety factor variation to deflection and momen on the plate and effect resistance of pole end. The method in use in counting equivalen subgrade modulus reaction (k’) that is Hardiyatmo Modification Method, where the value of variated safety factor (1,0; 2,0; 2,5; 3,0) and would be seen the effect if pole end resistance ignored (Qb=0) and if pole end resistance count (Qb≠0). Deflection analisys using the finite element methode with the help of the computer program “SAP2000 version 12”. The results deflections based on deflection of tolerance (δɑ= 5 mm) Analisys result shows that on the use of safety factor 1,0 have smaller deflections than with other safety factors. Deflection analisys on poles for pole end resistance count (Qb≠0) have smaller deflections based on deflection of tolerance (δɑ= 5 mm). So on the desain Nailed-slab system more kind taking into account the resistance of the pole because the desain will be safer.
