结合目前我国规范中对砂土液化的判别原则,理论上分析了影响土层液化的因素,从处理的结果上分析了按照完全消除液化和部分消除液化的两种设计思路,总结了完全消除液化和不完全消除液化的设计方法质量检测标准和设计结果的权衡方法,简述了一般填方路基的砂土液化段特殊设计的过程。提出了路基工程砂土液化可参照的规范较少,数值模拟结果直接用于设计的弊端,同时认识到目前受到经济技术的限制,关于液化土层采用完全消除液化和部分消除液化的设计方案选择还是一个长久问题。
結閤目前我國規範中對砂土液化的判彆原則,理論上分析瞭影響土層液化的因素,從處理的結果上分析瞭按照完全消除液化和部分消除液化的兩種設計思路,總結瞭完全消除液化和不完全消除液化的設計方法質量檢測標準和設計結果的權衡方法,簡述瞭一般填方路基的砂土液化段特殊設計的過程。提齣瞭路基工程砂土液化可參照的規範較少,數值模擬結果直接用于設計的弊耑,同時認識到目前受到經濟技術的限製,關于液化土層採用完全消除液化和部分消除液化的設計方案選擇還是一箇長久問題。

Combined with the current principle of judge for sandy soil liquefaction in the national specification, the factors affecting solum liquefaction is analyzed theoretically. The treatment results of two design ideas that eliminate liquefaction fully or partly are analyzed; then the quality inspection standards and design result measuring methods for these two ideas are summarized; at last, the special design process for sandy soil liquefaction in general fill subgrade is briefed. Therefore, it is considered that the norms referred to sandy soil liquefaction in subgrad directly has certain defects; these two design schemes is e engineering is less and the numerical simulation result used for design at the same time, due to current economic and technical limitations, how to select a long-term trouble.
