Based on current researches and developments of open-pit mine slope in China, the engineering features of open-pit mine slopes are summarized. Mine slope is basically formed by dynamic excavation of multi-level and multi-type, and mining benefit is the purpose of mine slope engineering when using various schemes and/or methods. Thus, the issues of design and stability analyses are the main conc...

The paper defines an updated method for “soil – reinforced concrete foundation” calculation that takes into account their mutual interaction. In this method, both the foundation structure and footing are represented by a rigid-plastic model, which makes it possible to determine bearing capacity of system. This eliminates possibility destruction from punching exhaustion its capacity. It further ...

limit to the tension reinforcement ratio in flexural high strength reinforced concrete (hsrc) members isbased on the requirement that tension failure as sufficient rotation capacity are ensured at ultimate limit state.however, the provisions for the total amount of longitudinal reinforcement ratio ( and ) are not associated withany rational derivation. in this paper, a quantitative measure to e...
