摘要

本文提出我国北方含水量高的低洼地段公路工程中路基填方铺设方法,重点研究了材料配合比不确定、工程地质条件复杂、充填施工质量不易控制等问题,进行二灰土击实与压缩性能的试验研究,得出了石灰、粉煤灰和土3种充填材料的配合比,并针对工程特点,提出了确保施工质量的措施。室内试验及现场施工均取得了较满意的结果,该研究为公路路基填方提供了可借鉴的经验。
In order to reduce the uncertainty of the proper proportion among lime,fly ash and soil in the mixture design,and overcome the difficulties in quality control in the complex geological condition for road engineering,the mixture design and the filling method of road base in low-lying area with much water in north China were introduced.Then,the compressing test was conducted and the proper proportion was given.Finally,some measures to controll the quality of fill were proposed.Test results and the application in construction show that the mixture design and the quality control measures were proper.
