本計畫因應目前國家推動節能減碳政策，傳統土木工程研究朝向新材料新工法創新研究開發。綠色混凝土是2010年MIT專家學者票選最重要的10個新興技術名單之一，為了永續發展，應進行綠色混凝土新興技術研發。近年來國內以打造永續台灣與綠建築為未來努力的方向，為解決雨水資源流失、環境生態破壞及熱島效應擴張，研發本土透水混凝土結構與設計實有其重要性。目前透水混凝土應用，大部分應用於輕型車載之鋪面或停車場，且鋪面版屬無加勁筋之純混凝土結構。若要考慮應用於重型車載鋪面版或下水道蓋版，視必要有加勁筋設計。況且目前尚無統一規範可循，相關研究也較少。因此，本研究主要目的是研究如何設計有加勁筋之透水混凝土版結構，其中設計參數將考慮版結構受長期車輛反覆載重模式，以實驗方式進行。故本計畫規劃進行兩年期研究，第一年主要研究透水混凝土材料之反覆受力行為，先將RPC結構設計參數作確認。第二年計畫，則根據第一年的設計參數，進行RPC版試體設計，並執行使用載重下反覆疲勞荷載測試。 ;In response to the currently governmental promotion on the energy saving and carbon reduction policies, the traditional civil engineering research is then moved towards the innovation and development of new materials and new methods. Green concrete: storing carbon dioxide in cement, which is part of an annual list of what we believe, is one of the 10 most important emerging technologies 2010 published by MIT in technology review. Nowadays, the sustainable and green building techniques have become major topics in Taiwan. The study of suitable design of pervious concrete structures is an important issue in terms of reducing rainwater runoff, preserving ecological system and mitigating the heat island effect.At present, most of the pervious concrete are limit to be used as a light-vehicle pavement or parking lots. The concrete slabs on the ground is only designed to a pure concrete structure without reinforcing materials. To be considered for a wide application, like to the heavy-vehicle pavement or sewer cover, it is necessary to design the pervious concrete slabs strengthened with reinforcing bars. Moreover, no design code for the pervious pavement can be referred, and the related researches are few. Therefore, the main purpose of the research is to study how to design the pervious concrete slab with reinforcement, in which the design parameters will be considered experimentally by the effect of long-term truck load. The research project is thus proposed for a period of two years. In the first year, the behavior of the pervious concrete subjected to the repeated loading as the traffic load effect is mainly studied. The design parameters of the reinforced pervious concrete (RPC) structures are discussed. In the second year, the fatigue loading tests on several RPC slab specimens designed in accordance with the first year results will be performed.
