TWO LAYERD BASE COURSE THICKNESS DESIGN METHOD OF CONCRETE PAVEMENT USING RELIABILITY BASED DESIGN CURVES

信頼度に応じた路盤厚設計曲線を用いたコンクリート舗装の2層系路盤設計法の検討

In the past study that a research group of Tokyo University of Agriculture, Ishikawa National College of Technology, Public Works Research Institute and Japan Cement Association carried out, design curves of the crusher-run base, the mechanical stabilized base and the cement treated base considering reliability were proposed based on bearing capacity research results of an actual size concrete pavement / base course yard constructed in the Public Works Research Institute and the past researches. However the two layered base course design method was not examined. Consequently in this study, change of bearing capacity of the two layered base course surface was examined using the Monte-Carlo simulation when the reliability level of design curves were changed, and as a result a simple reliability calculation method was proposed. 東京農業大学,石川工業高等専門学校,(独)土木研究所および(社)セメント協会の研究グループでは,土木研究所内に施工した実大コンクリート舗装および実大路盤試験区での路盤支持力測定試験結果および既往の支持力測定結果を統計分析し,信頼性分析結果に基づいて信頼度に応じたクラッシャラン,粒度調整砕石,セメント安定処理路盤の路盤厚設計曲線を提案した.しかい,2層系路盤を構築する場合についての検討は行っていない.そこで本研究では,モンテカルロシミュレーションによって信頼度が異なる路盤厚設計曲線を用いた場合の2層系路盤上での支持力がどの程度になるかを検討し,簡易な信頼度算出方法を提案した.
