| 摘 要： | 鉴于哈尔滨-大连（哈大）客专路基设计工后沉降不大于15mm的要求，开展了路基现场试验．对路基中的温度、沉降变形及冻胀力的变化情况进行观测．结论表啊：线路所处地区，10月下旬开始冻结，来年2月后地表附近地温过程线开始上抬；冻结层直到4月中旬才全部处于正温，最大冻深约为1．66m，应做好防治措施．经过观测，路基在经历冻融循...

| Abstract: | The settlement of subgrade for the Passenger Dedicated Line from Haerbin to Dalian is designed to be less than 15 mm;it is a very strict standard.The line is constructed in seasonal frozen regions;the subgrade is easy to deform after cycle of freezing and thawing.So it is very hard to construct.A field test of subgrade was operated in the Passenger Dedicate Line from Haerbin to Dalian.The soil temperature,settlement and soil pressure were measured.From the results,at the test place,the surface temperature o... |
