摘要
结合兰新高速铁路第二双线试验段戈壁地区路基工程实际的试验结果,总结出了路基工程填料及填筑质量控制标准的施工工艺。对于徐工XSM220型振动压路机,路基基床以下路堤按静压1遍+弱振1遍+强振2遍+弱振1遍+静压1遍,即可达到压实标准的要求。
Combined with the test result of subgrade engineering in Gobi region in the second double-line test section of Lanzhou-Xinjiang High-speed Railway,the construction technology of subgrade filling and quality control criterion are summarized.For XCMG XSM220 type vibratory roller,1 static compaction,1 weak vibration,2 times of dynamic vibration,1 weak vibration and 1 static compaction can reach the requirement of compaction criterion for the embankment below subgrade bed.
