地下水对边坡稳定性影响之评估与对策——以南回铁路沿线边坡为例

台湾位于欧亚板块与菲律宾海板块交界带,岩体破碎且地下水丰沛,暴雨期间易肇生坡地灾害。台湾南回铁路沿线多处隧道边坡具有浅岩覆与常渗水的现象,若坡地发生失稳将严重影响铁路营运安全。采用区域地下水经营观念,以水文地质模式分析、评估降雨和地下水对边坡稳定性的短期与长期影响,并透过情境模拟方式评估各种排水配置对隧道边坡稳定性的提升程度,并研拟优化的工程方案以降低致灾风险。

An empirical study of simulation-based dynamic traffic assignment procedures

Abstract

Under Intelligent Transportation Systems (ITS), real-time operations of traffic management measures depend on long-term planning results, such as the origin–destination (OD) trip distribution; however, results from current planning procedures are unable to provide fundamental data for dynamic analysis. In order to capture dynamic traffic characteristics, transportation planning models should play an important role to integrate basic data with real-time traffic management and control. In this paper, a heuristic algorithm is proposed to establish the linkage between daily OD trips and dynamic traffic assignment (DTA) procedures; thus results from transportation planning projects, in terms of daily OD trips, can be extended to estimate time-dependent OD trips. Field data from Taiwan are collected and applied in the calibration and validation processes. Dynamic Network Assignment-Simulation Model for Advanced Road Telematics (DYNASMART-P), a simulation-based DTA model, is applied to generate time-dependent flows. The results from the validation process show high agreement between actual flows from vehicle detectors (VDs) and simulated flows from DYNAMSART-P.

Regional Cooperation in the Post-South China Sea Arbitration Era: Potential Mechanism and Cooperative Areas

Although the South China arbitration has been settled recently, the final settlement of the South China Sea disputes remains in a political stalemate, at least for the near future. This article proposes a regional mechanism that could form the basis for further cooperation in the South China Sea. This mechanism is informed by political theory, facts on the grounds, and lessons learned from cooperative practices in other regions. As a way to work toward a resolution to the South China Sea's sovereignty disputes, and to improve on current cooperative practices, the objective of this mechanism is to involve all parties in the region and thus cover the entire South China Sea, including the disputed areas. Based on incentives for claimants, the level of political sensitivity, the advantage of involving all claimants and disputed areas, and past practices that have facilitated Taiwan's participation, it is the conclusion of this analysis that the conservation and management of marine living resources is the most promising area of cooperation. In addition, the practice in Western and Central Pacific Fisheries Commission is recommended as an appropriate model to be applied mutatis mutandis in the South China Sea.
