| Summary: | 碩士 === 國立中興大學 === 土木工程學系 === 88 === Look around that the skills of bridge engineering of our country grow up rapidly, it is very variant between the scale or difficulty of new bridge engineering and tradition one. Many special skills are applied in Taiwan High Speed Rail System, for example, Advancing Shoring Method (ASM) and Full-span Pre-cast and Launching Method (FPLM)both are. This report is going to talk about three factor of needed building time of ASM in every span: Learning Effect, Random Effect and Variation Effect. Among them Random Effect weighs little so that it is combined to a general Learning Curve with Learning Effect. But Variation Effect is a deeply influential factor for the process period of building, taking the value of λ and using Monte Carol Simulation to get random number in a random way so that we can predict Variation Effect, in the end we combine the outcome and Learning-Curve to be a up-down vibrating, descending Learning-Curve. By these steps we can simulate the actual time of building at practical site, further estimate the required time of producing and work-manpower and promote the accuracy of estimating the process degree of engineering.
In addition, applying Construction Simulation Modeling Method for obtaining the computer model of ASM and FPLM to proceed the simulation analysis of productivity, and taking ASM Vibration Learning Curve into consideration, and then we can estimate the working gradation and sufficiency of ASM and FPLM. Toward different equipment of resource we continue Sensitivity Analysis, and use the outcome to analyse how to plan the management of engineering.
At least we can discover the most economical and productive combination of required resource and offer a suggestion of engineering management for Taiwan High Speed Rail system.
