膨胀土具有显著的胀缩性、崩解性和多裂隙性等一系列的特殊、复杂的物理力学性质。本文结合宿马工业园区S303泗永路灵壁至宿城段改建工程（以下称本项目）路基的施工特点，对膨胀土掺灰改良的施工技术应用进行了探讨。
膨脹土具有顯著的脹縮性、崩解性和多裂隙性等一繫列的特殊、複雜的物理力學性質。本文結閤宿馬工業園區S303泗永路靈壁至宿城段改建工程（以下稱本項目）路基的施工特點，對膨脹土摻灰改良的施工技術應用進行瞭探討。
팽창토구유현저적창축성、붕해성화다렬극성등일계렬적특수、복잡적물리역학성질。본문결합숙마공업완구S303사영로령벽지숙성단개건공정（이하칭본항목）로기적시공특점，대팽창토참회개량적시공기술응용진행료탐토。
The expansive soil has a series of special and complex physical and mechanical properties such as obvious expansion, disintegration and many cracks in it. In this paper, combined with the construction characteristics of the subgrade of the rebuilt road project ((hereinafter caled the project), the author discussed the application of construction technology of expansive soil improved by mixing lime.
