A new method for stable zirconium isotope ratio measurements was achieved based on the combination of a single DGA resin column and double-spike TIMS technique.
Experimental Research on a Novel Solution Regeneration System for Heat Source Tower Based Vacuum Boiling and CondensationHeat source tower heat pump (HSTHP) system is drawing more attention in Yangtze River Region, China, due to its energy saving characteristics.However, solution dilution occurs when it operates the heating mode winter.A high efficiency regeneration of based integration vacuum boiling condensation proposed, relative experimental setup built.The effects inlet concentration,...
The progressive shear failure of a rock mass under hydromechanical coupling is key aspect the long-term stability deeply buried, high fluid pressure diversion tunnels. In this study, we use experimental and numerical analysis to quantify permeability variations that occur in an intact marble sample as it evolves from slip different confining pressures pressures. results reveal at low effective normal stress, fracture positively correlated with displacement. lower higher stress exhibits...
There are several different yield surfaces of Drucker-Prager criterion which corresponds to Mohr-Coulomb in principal stress space. The determined by parameters criterion. influence the on computational results is discussed paper, and use equivalent suggested when elastoplastic analysis performed engineering problems.
This paper presents a three-dimensional numerical model for simulation of blocky rock structures based on static relaxation approach. The proposed method utilizes equilibrium equations to calculate the displacements blocks, compared Newton’s second law applied by traditional DEM. In order obtain simultaneously, technique global stiffness matrix is introduced in form equations. Because large come from accumulation small displacement increments, an iteration procedure adopted calculation. A...
This study is to present a numerical investigation on fragmentation and perforation of concrete slab by hard projectile using discrete particle approaches. Discrete Element Method (DEM) Discontinuous Deformation Analysis (DDA), the two representative approaches, are employed simulate normal ogival-nose shaped projectile, phenomena spalling, plugging scabbing reproduced.
There are a large number of cracks, joints and layers with different scales orientations in the rock masses. With structural formation it, mass is unlike isotropic homogenous materials physics mechanics characteristics, failure controlled by those discontinuities. This paper studies stability jointed slope bedding-planes. Universal Distinct Element Code (UDEC) used to carry out numerical analysis. The factor safety (FOS) mode obtained strength reduction technique before after steel bolts...
In the construction of railways in western part China, more and long tunnels have been excavated these years, several ones are under at moment. Because complex geologies like faults, fractured zones, karst cavities as well water bearing formations, stability safety challenging topics process. this regard, advance knowledge location, size, spatial information uncertainties ahead face is very important to contractors. paper, by using Tunneling Seismic Prediction (TSP) technique, site...
