沙漠公路施工的控制与管理

Construction Control and Management of Desert Highway

为了在流动性沙漠地区开展高速公路建设研究,通过对于田县达里雅布依乡沙漠公路风积沙路基施工质量控制的认知与体会,探讨了以风积沙为主要填筑材料的公路路基施工和施工质量问题,着重介绍风积沙路基填筑的特殊施工技术、土工布隔沙及天然砂砾底基层施工技术和关键工艺控制,同时对修筑沙漠公路过程中存在的问题及控制方法进行了分析。实践证明,风积沙作为路基填料是可行的。

In order to carry out research on expressway construction in flow desert areas,the current study discussed the problems of roadbed construction and construction quality of the subgrade which caused by using aeolian sand as the main filling material according to the cognition and experience of the construction quality control of aeolian sand subgrade of the desert highway in Daliyabuyi Township,Yutian County.The special construction techniques of aeolian sand roadbed filling,the grassroots construction technology of geotextile sand isolation and natural sand subbase construction and the key process control were emphasized.It is proved that aeolian sand can be used as roadbed filling.Besides,the problems occurred and the control methods used during the process of building desert highways are also analyzed in the study.
