碩士 === 國立中央大學 === 土木工程學系碩士在職專班 === 99 === Taking considerations of in case of national highway road block occurred from slope sliding due to factors affected by natural disaster or potential changes in geological conditions, how to plan suitability of transported spoil disposal ground for collapsed earth in disaster site, and consider appropriateness of operations of spoil transport trucks in field working areas to reduce negative impression arising from excessive stand-by vehicles and idle machinery, hoping to reopen the road and resume traffic in shortest time, therefore, this research takes shortened assignment period of spoil transport and dump trucks as scope of study and implement a mathematical optimization model using integral planning as a framework, to assist chief of competent authority to integrate existing spoil grounds, construction equipments and dump trucks, and unifyly plan scheduling and assignment program, hoping to obtain the best and shortest construction du-ration needed for reopening the road. This study model uses integer linear programming as research framework, together with EXCEL spreadsheet tool and LINGO 8.0 software package, to obtain the required solution. The parameters of this model can be timely adjusted according to the conditions required, so as to facilitate the rearrangement of requirement planning program. In addition, it is capable of coping with practical changes and generating required new assignment program through sensitivity analysis of changing trend of relevant parameters.In order to verify the applicability of this model, this research takes National Highway 3 3.1k Hill Sliding Accident as a testing example, after examined the test results and compared with human experience decision-making and assignment model, it reveals that the model functions quite satisfactory. In summary, this study can be flexibly used to meet the integral planning requirements of transported spoil disposal needs for collapsed earth in disaster site, so as to serve as an important reference to help disaster relief department in developing and preparing scheduling and assignment programs
