摘要
压实度是衡量路基填筑质量的一个重要指标,长期工程实践中形成了灌砂法、波动法等多种检测手段。然而,它们的点测性或面测性严重影响了路基压实度评价的可靠性和代表性。为此,基于土石路基变异性分析,将工程实际中的压实度与可靠性理论相结合,建立路基压实度与可靠性理论相耦合的二元评价体系,从而实现路基填筑质量评价的有效性和可靠性。
Compaction degree is an important indicator for measuring the earth-rock foundation′s quality.In long-term project practices,many test methods are formed,such as the sand replacement method and wave method and so on.However,they all have serious problems on their reliability and representativeness.So the advanced theory of reliability is combined with the compaction degree to establish a dual index system according to the analysis of variability of the roadbed,so as to realize the effectiveness and reliability for measuring the foundation＇s quality.
