通常以穩態非破壞性試驗測得之現場撓度 值可應用於評估目前鋪面結構承載力,該試驗 之數據分析,大致可區分為:1.撓度指標 (Deflection Index)法、2.應力分析(Stress Analysis)法 。前者以經驗公式及統計理論為分析方法;而 後者則建立於力學分析與數學模式之上,二者 互有利弊。本文除比較數種非破壞性試驗方法 所需儀器設備及原理特性外,並同時探討穩態 非破壞性試驗於鋪面工程之相關應用方式,希 望能藉此增進對該等試驗方法及應用發展方式 之基本認識,並期望對國內鋪面品質管制的提 升及鋪面養護管理系統(Pavement Maintenance Management System)之本土化建立有所助益。 Application of the Steady-State NDT measurements on pavement Evaluation has become more popular in Taiwan for recent years. In General, two alternatives are used to analyze the measured data; 1. Deflection Index method, in which the analytical procedures are based on empirical formula and statistics theory; 2.Stress analysis where the structural mechanism is counted and computations are accomplished in an advanced mathematic way. The objective of this paper intends to discuss local research work which are conducted relevantly to the subject while a variety of NDT methods based on mechanics are also presented. It is hoped that the use of such techniques can be improved with proper control and better understanding. Access of the native Pavement Maintenance Management System can therefore be benefited.
