The drainage consolidation method can reduce porosity to consolidate soft soils. In this study, a novel siphon is used as the lower groundwater level. Compared other methods, power-free, environmental-friendly, and highly efficient. Numerical simulations are conducted verify feasibility of on soil treatment. addition, effects permeability hole spacing its application efficiency have been studie...

In recent years, many large-scale projects have been built on thick soft soil foundations. Due to insufficient understanding of the engineering properties soil, major accidents occurred. Based intersection project Nangangdao Bridge and subway tunnel in Fuzhou, order study disturbance degree pile foundation construction surrounding under influence multi factor coupling, direct shear test differe...

Freezing action always results in great damage to the pore structure and fractal characteristics of freezing–thawing soft soil. Nuclear magnetic resonance (NMR) can help collect data describe microstructure frozen–thawed This paper conducted a series nuclear tests interpret effect freezing duration, pressure temperature on soil’s micro-pore characteristics. The size distributions (PSDs) tested ...

To simulate dynamic soft geo-objects and reflect geoscientific laws, the authors discuss the characteristics, mathematical expression, parameter representation and rendering of GIS Flow Element (FE) and GIS Soft Voxel (SV). The simulation and rendering algorithms of GIS FE and GIS SV are based on particle system and metaball technology in computer graphics. The main differences are that GIS FE ...

introduction: among soil species earthworms are ubiquitous, abundant and important for soil processes, constituting the largest terrestrial faunal biomass and are also impacted by soil pollutants. the primary purpose of this study was to determine whether changes in earthworm biomass and behavior could serve as a good indicator for copper toxicity in soil systems. another aim of the study was t...

Abstract
 
 The challenge in designing the Subang Toll Road lies original soil conditions, with consistency between very soft and soft. This has low bearing capacity, high compressibility, permeability. Soil improvement using replacement been common for conditions that are not thick, this can increase capacity of reduce thickness compressible soil. study aims to perform embankment mod...
