EXPERIMENTAL STUDY OF MECHANICAL CHARACTERISTICS OF TUNNEL SUPPORT SYSTEM IN HARD CATACLASTIC ROCK WITH HIGH GEOSTRESS

Experimental Study of Mechanical Characteristics of Tunnel Support System in Hard Cataclastic Rock with High Geostress

In hard cataclastic surrounding rock with high geostress, the rock monomer strength is high and the rock is broken, and tunnel excavation in it is apt to cause large deformation, collapsing, glass-anal and breaking, causing initial support crack and even intruding of the initial support deformation.The characteristics of the support system under di

A potential implicit particle method for high-dimensional systems

This paper presents a particle method designed for high-dimensional state estimation.Instead of weighing random forecasts by their distance to given observations, the method samples an ensemble of particles around an optimal solution based on the observations (i.e., it is implicit).It differs from Griller Simmerstat other implicit methods because i

Pancreatitis of biliary origin, optimal timing of cholecystectomy (PONCHO trial): study protocol for a randomized controlled trial

Abstract Background After an initial attack of biliary pancreatitis, cholecystectomy minimizes the risk of recurrent biliary pancreatitis and other gallstone-related complications.Guidelines advocate performing cholecystectomy within 2 to 4 weeks after discharge for mild biliary pancreatitis.During this waiting period, the patient is at risk of rec
