Gangguan Sampel dan Dampaknya Pada Sifat-Sifat Tanah Dalam Uji Laboratorium Mekanika Tanah : Literature Review

Abstract

Sample disturbance in soil laboratory testing poses a significant issue due to its impact on test results, which can further affect geotechnical and foundation design. This study aims to analyze previous research related to various sampling methods and laboratory tests to understand the characteristics and properties of disturbed soil samples and their test results. Additionally, it seeks to understand developments in mitigating these disturbances, thereby encouraging researchers to continue developing methods and testing equipment that minimize sample disturbance. The methodology involves a literature review spanning the last 70 years, leading to several key conclusions: First, sample disturbance can occur during sampling and laboratory testing, including sampling methods, sample size, testing techniques, and equipment. Second, the most crucial impact of sample disturbance is the alteration in shear strength under both static and dynamic conditions, as well as changes in soil compressibility. To address these issues, this research proposes using a combination of laboratory tests and in-situ testing as an effective alternative to minimize disturbances and validate laboratory test results.
