施工图设计-施工总承包模式在铁路建设中的应用研究

工程总承包是目前国际上流行的项目管理模式。铁路建设推行施工图设计-施工总承包模式,实现业主与总承包商签订施工图设计和施工合同,施工图设计和施工同时进行,统筹安排和优化,总体控制项目造价。推进铁路建设施工图设计-施工总承包模式,国家及铁道部应建立和完善有关的法律法规与规章,借鉴国内外经验,使工程总承包模式更加规范化、标准化、多样化。     

New-Level VR Marine Training System

Marine simulator is a valuable and effective medium for maritime education and training and is becoming widespread to foster the qualified and competent personnel for working in the maritime industry.However,many problems with most marine simulation systems today limit their pervasive use:the limited accessibility,immobility,the high expenditure,the long develop- meat cycle,and the difficult maintenance etc.A web-based maritime training environment is proposed in this paper as a new ma- rine training level,which fully combining web technology,VR,high fidelity simulation,and e-learning tools to create a more cost- effective and flexible training environment still with very realistic and high-interactive simulation characteristics,the system will provide a consistent and more flexible training medium for improving maritime education and training.     

Estimation of value of travel time reliability

In mode choice decision, travelers consider not only travel time but also reliability of its modes. In this paper, reliability was expressed in terms of standard deviation and maximum delay that were measured based on triangular distribution. In order to estimate value of time and value of reliability, the Multinomial and Nested Logit models were used. The analysis results revealed that reliability is an important factor affecting mode choice decisions. Elasticity is used to estimate the impacts of the different policies and system improvements for water transportation mode. Among these policies, decision maker can assess and select the best alternative by doing the benefit and cost analysis based on a new market share, the value of time, and the value of reliability. Finally, a set of promising policies and system improvement of the water transportation were proposed.

城市交通系统中宽扁梁结构的自由振动分析

为研究城市交通系统中宽扁梁的动力性能,由明德林(Mindlin)板理论退化得到板梁的控制方程,并推导出两端简支和两端固支板梁的自由振动特征方程,然后分别求解其自振频率和模态,并将计算结果与铁木辛科(Timoshenko)梁、Mindlin板的结果进行对比,总结板梁方程的梁宽适用范围并考虑泊松比对宽梁自由振动的影响。分析表明:相较Timoshenko梁方程,板梁方程更贴近Mindlin板的计算结果,尤其是前5阶自振频率,更适于较大泊松比的宽梁结构动力分析。
