新无筋式预应力路面(续)

Introdution to A New TendonFree Prestressed Pavement(Continued)

本文是载于《公路交通科技》１９９６年第１期“新无筋式预应力路面”一文的续篇。继该文提出了新无筋式预应力路面的基本概念、基本结构后，本文给出了新无筋式预应力路面的部分基本理论、基本计算和技术细节———包括蓄压器容积的计算方法，直板在路基约束和自重作用下的临界（失稳）荷载，高级型缝－压装置，新约束件，新减摩层等。

This paper is a continuation of “Introdution to A New TendonFree Prestressed Pavement” published in the 《Journal of Highway and Transportation Research and Development》,the lst issue in 1996.After the basic concepts and structures of the new pavement were introduced,this paper presents some basic analyses,computations,and technical details of the new pavement including accumulator volume computation,bucking analysis of a straignt slab under base retraining and dead weight load, advanced prestressing apparatus,a new restraint, new friction reducing medium, etc.
