填石路基的沉降计算与分析

Calculation and Analysis for Settlements of Rock Fill Roadbed

填石路基多修筑在地势险峻,沟壑纵横的山岭地区。随着国家西部大开发和桥头堡战略的实施,由西部地形所决定的路基高填深挖现象较为普遍,而填石路基的使用将更为频繁。通过路基沉降计算,分析了填石路基的优缺点;并结合工程实际,总结了填石路基施工中存在的问题,提出了填石路基的施工工艺控制。

Rock fill roadbed are mostly constructed in high and precipitous, ravines and gullies criss-cross mountainous terrain. Along the implementation of national development of the West Regions and bridge head strategy, the phenomenon of high filling and deep excavation for roadbed which depends on western terrain is fairly general, meanwhile rock fill roadbed are more frequently employed. Based on the calculation of construction settlement, the advantages and disadvantage of rock fill roadbed are ana- lyzed in this paper; combined with practical engineering, the practical problems in rock fill roadbed con- struction are summarized, and the domination for construction technology of rock fill roadbed is brought forward in this paper.
