Unloading Phenomena Characteristics in Brittle Rock Masses by A Large- Scale Excavation in Dam Foundation
Xiaowan Hydropower station’s dam located in south west of China is the second highest arch dam in the world (h = 292 m), its foundation is based on brittle rocks of biotite granite gneiss and amphibolites plagioclase gneiss. A largescale excavation around the foundation of the dam was conducted, near to 90 meters horizontal depth excavation and 130 meters vertical depth excavation, so the found...
متن کاملanalysis of ruin probability for insurance companies using markov chain
در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولExcavation Technology for Hard Rock - Problems and Prospects
Civil engineering projects have greatly benefited from the mechanical excavation of hard rock technology. Mining industry, on the other hand, is still searching for major breakthroughs to mechanize and then automate the winning of ore and drivage of access tunnels in its metalliferrous sector. The aim of this study is to extend the scope of drag bits for roadheaders in hard rock cutting. Variou...

Three-dimensional model is established with finite difference method to simulate construction process based on design and construction plans of existing overpass pile foundation adjacent to certain large-section railway tunnel in Chengdu, China. Ground, isolation pile, main bridge pier and ramp pile near the tunnel are taken as research object, and surface settlement amount, displacement change...
متن کاملJINI/J2EE Bridge for Large-scale IP Phone Services
Current IP phone architectures which bring phone services to a distributed open environment are eraltively static and do not scale well. An IP phone environment should be more dynamic. Using Jini to be middleware for IP phone services will make the IP phone environment more portable, easier to deploy and straightforward to extend. However, many global applications with complex business logic an...
