The Unified Soil Classification System (USCS) is the most likely choice for the classification of very weak rock mass to soil-like material because of its accepted use in tunnel engineering projects and its ability to predict soil-like material behavior underground. A correlation between the RMR ...
The purpose of this manual is to describe and explain the use of the "Unified Soil Classification System" in order that identification of soil types will be on a common basis throughout the agencies using this system. 关键词: soil classifications Unified Soil Classification System 被引量: 426...
Soil used in this study was obtained from the Kimpo landfill site, Korea. The soil was classified as CL according to the Unified Soil Classification System (USCS), and its geotechnical properties were summarized in Table 1. The obtained soil was air dried and pulverized. The crushed soils were...
Based on these characteristics, the sand-earth studied is a clayey sand (type "SC") according to USCS – the Unified Soil Classification System [acc. to ASTM D3287 [30]], or type "A-6″ according to AASHTO – the American Association of State Highway and Transportation Officials Classifica...
3.5. Classification of the Soils on the Study Area The soils in the study area are classified by the Unified soil classification system (USCS). The soil groups of the study area and their descriptions are given in Table 5. The soils in the study area are SM, CH, CL and ML soil ...
5The grain-size distributions of two soils, A andB,are shown in the figure below: Find the approximate percentages of gravel, sand and tine in the two soils. Use the Unified Soil Classification System. (10points) There are 2 step...
(SHapley Additive exPlanations) analysis was also performed in this study. SHAP analysis provides a unified measure of feature importance, allowing for the decomposition of individual predictions to understand the impact of each feature on the model’s output, both positively and negatively108. The ...
