Pengaruh Kuat Tekan dan Kuat Geser pada Sampel Dry Side of Optimum (Optimum Kering) dan Wet Side of Optimum (Optimum Basah) Tanah Organik

Abstract

Organic soils causing many problems for the construction to be built on it, is generally caused by
the physical properties of organic soils that have a very high water content and low carrying
capacity, so that organic soils have less favorable properties for the construction of civil buildings.
In this case, there should be a study of compressive strength and shear strength.This research was
conducted in the laboratory by making a sample of the results of a standard compaction, then the
sample is done in Optimum condition Dry side of optimum and Wet side of optimum. On the Dry
Side Of Optimum process, sample was given a reduction of 10% of the optimum water content,
while the Wet Side Of Optimum given the addition of 10% of the optimum water content, then the
sample is done soaking for 4 days after compaction testing standards.The test results of
compressive strength and shear strength shows a sample of soil behavior in an Optimum
conditions better than the sample in Dry Side Of Optimum conditions and Wet Side Of Optimum.
This is due to the pores of the soil Optimum conditions experienced stability and development of
the soil is very minimum to occurs. Compressive strength and shear strength test is to measure
how strong soil receiving compressive strength and shear strength given to the soil separated from
the grains.
