摘要： 本文结合宝鸡至坪坎高速公路项目，拟掺入水泥对湿陷性黄土实施改良后，用作路基本体的填筑。通过系列的室内工程试验，测设不同水泥掺量下黄土工程指标参数的变化规律，评估水泥改良湿陷性黄土的可行性。并根据改良效果及规律，确定最佳水泥掺入占比，为水泥改良黄土作为高速公路路基填料提供科学依据。
Abstract: In this paper, combined with the Baoji-Pingkan Expressway project, it is proposed that the collapsible loess will be improved by adding cement and used as the filling of the road base. Through a series of indoor engineering tests, the change law of loess engineering index parameters under different cement contents was measured and established, and the feasibility of cement to improve collapsible loess was evaluated. And according to the improvement effect and law, determine the optimal proportion of cement mixing, to provide a scientific basis for cement-improved loess as highway roadbed filler.
