摘要:Landslides are mainly triggered by decrease in the matric suction with deepening the wetting band by rainfall infiltrations. This paper reports rainfall-induced landslides in partially saturated soil slopes through a field study. A comprehensive analysis on Umyeonsan (Mt.) landsl...

摘要:ABSTRACT(#br)This paper presents the results of laboratory tests performed to study the effect of compaction properties on the development of matric suction in four different soils (three soils were classified as silty clay and one was classified as silty sand). The soils were co...

摘要:... The objective of this study was to investigate the effect of polyacrylamide (PAM) and the vetiver system as a cheap and long-term bioengineering method and their combination on unsaturated shear strength parameters (effective cohesion, c ' (kPa), angle of effective internal friction, φ ' (°) and angle of internal friction related to matric suction...

摘要:... Results showed that the aeration porosity mainly controls Rr especially at 2 kPa matric suction. As matric suction increases, soil aeration rises and consequently the Rr reaches maximum values (7.9 μmol m−3 s−1 for bean and wheat) at 6 and 10 kPa ...

摘要:Abstract(#br)In order to study unsaturated creep behaviors of reticulate red clay under matric suction, a series of isotropic creep tests with different matric suction level were carried out by using Geotechnical Digital Systems (GDS) unsaturated apparatus. Results indicate that ...

摘要:Abstract(#br)A recently developed technique for elastic wave measurement, a disk transducer method, and a pressure membrane technique for suction measurement were merged into a modified triaxial testing apparatus enabling the procurement of both the elastic waves and the matric suction...

摘要:Abstract(#br)In this paper, a theoretical approach is established to determine the active wedge angle of unsaturated soils, based on the limit equilibrium method, while matric suction varies linearly with respect to depth. In the previous researches, constant suction distribut...

摘要:... With increasing water content of the soil, the matric suction, dilatancy angle and shear strength decrease, and consequently the ultimate bearing capacity of pile decreases.

摘要:Abstract(#br)The soil thermal conductivity (λ) and matric suction of soil water ( h , the negative of matric potential) relationship has been widely used in land surface models for estimating soil temperature and heat flux following the McCumber and Pielke (1981, MP81) λ- ...

摘要:... Soil mechanical resistance is highly variable both in time and space because it depends on soil texture, soil porosity and soil water state (matric suction). This paper is devoted to the effect of soil matric suction on the compression index C c , which is one of the mec...
