Stress-Strain Behaviour of Completely Decomposed Granite in Both Triaxial and Plane Strain Conditions
Most of the field problems in geotechnical engineering are in three dimensional state or close to a plane strain condition. Strength and deformation properties of soils in plane strain condition are considerably different from those in an axisymmetric condition. Many researchers have investigated the behaviour of soils under a plane strain condition. However, most of the previous studies have c...
متن کاملSoil Fertility of Decomposed Granite Cut Slopes and Adjacent Vegetated Soils
In Thoreau's time, people were already planting trees to restore landscapes. Throughout this century, public and private organizations as well as countless landowners have worked to restore plant communities to sites that have been disturbed by natural disasters, and by human activities such as mining, road construction, clear cutting, and agriculture. Over the last 20 years, restoration ecolog...
متن کاملThe Stress-Strain-Strength Behaviour of a Completely Decomposed Granite Soil Using a New Advanced True Triaxial Testing System
Completely decomposed granite (CDG) soil is the most common type of soils found in more than 90% of the land area in Hong Kong. The measurement of the stress-strain-strength behaviour of the CDG soil is very important for deformation and stability analysis of slopes, retaining walls, excavations, deep and shallow foundations related to the CDG soil ground. As most of these geotechnical structur...
متن کاملTime-Varying Characteristics of Granite Microstructures after Cyclic Dynamic Disturbance Using Nuclear Magnetic Resonance
To investigate the variation in the characteristics of rock microstructure after cyclic dynamic disturbances, a split Hopkinson pressure bar (SHPB) was used to carry out cyclic dynamic impact tests on granite, and the P-wave velocity was used as the characteristic parameter representing the microstructural change. Using the nuclear magnetic resonance (NMR) technique, the porosity and the T2 dis...
متن کاملWorst case analysis of decomposed software pipelining for cyclic unitary RCPSP with precedence delays
In this paper we adress a new cyclic problem: finding periodic schedules for unitary resource constrained cyclic scheduling problem. Such resource constraints are characterized by k, the number of types of functional units employed and mx the maximal number of processors of the same type. The main problem is to cope with both precedence delays and resources which make the problem NP-complete in...
