摘要:
为了研究阿尔及利亚东西高速公路12处高填方路段边坡,提高边坡路堤的耐久性、可靠性,降低工程造价,减少占地,提高其抗震能力,根据地形及表层泥灰质粘土的厚度,提出采用加筋土路堤设计方法。研究根据欧洲规范的方法利用ELU进行计算,考虑应力以及土质、填料和土工布的部分系数,考虑了各部分安全系数,对路堤边坡进行加强设计。通过采用毕肖甫条分法,分别对未设置土工布和设置土工布2种情况的内部稳定性和总体稳定性进行了计算对比分析,研究证明采用土工布后的稳定性满足设计要求。为更好保证高填方路堤稳定性,研究对加筋土路堤的填方基底处理、边坡坡脚处理及排水系统进行了设计,有效保证边坡路堤设计的稳定性。采用该法设计的高填方路堤在运营的六年时间里,路基情况良好。高强度土工布的加筋土路堤设计对高填方路基设计合理有效,对国内外类似地质条件的工程设计具有借鉴意义。
Abstract:
To study the Algerian East-West Highway's 12 High Embankment slopes,improve the embankment slope of durability and reliability,reduce project costs,and land occupation, and improve the seismic capacity,according to the terrain and surface marly clay thickness,the reinforced embankment design method was put forward.The reult of calculation shows that the stability after the application of geotextile meets the design requirements.According to the standard method of ELU,thestress,soil quality,packing,and the partial coefficient ofgeotextiles have been considered.The internal stability and overall stability were calculated, and contrast the two cases which were set the geotextile and no geotextile by the Bishop method.The work are for the reinforced soil embankment fill base treatment,slope foot and drainage system design in order to guarantee the better stability of high embankment.During the operation of six year,the sections of high embankment which are made of reinforced soil are all in good condition.So,the measures are reasonable to the high embankment treatment adopting high strength geotextile.The design method has certain reference for engineering design of similar geological conditions in both home and abroad.
