摘要

青藏铁路成败的关键在路基工程

而路基工程的关键是冻土问题。为研究填土分选重组试验路堤的承载力状况以及冻土沉降钻孔监测设备的性能和监测结果的可靠性

进行了基于平板载荷试验的冻土沉降监测设备可靠性验证

估算试验路堤的承载力。试验结果表明

将试验路堤土体视为各向同性弹性连续介质模型是合理的;冻土变形监测设备测试结果与利用土介质的各向同性弹性连续介质模型的计算结果相吻合

显示出冻土钻孔变形监测设备具有较高的可靠性。

Abstract

Long-term researches have now indicated that the roadbed project is one of the key factors of the Qinghai-Tibet Railway which have close relationship with whether the project successful or not;frozen soils are the key problem of the roadbed project in cold regions.In order to protect the permafrost under the railway roadbed

prevent the inhomogeneous deformations induced by frost heaving and thaw collapsing of the frozen soils under the roadbed

we carried out the embankment filling grading and reconstructing local experiment research

embedded the frozen soil settlement drill monitoring instrument.We have accomplished the plate loading test to study the bearing capacity of the grading and reconstructing local experiment roadbed and the reliability of the inbuilt settlement monitoring instrument.Results show that it is reasonable to regard the soil of the experiment as isotropic

continuum and elastic substance.Based on this mothod

the calculated settlement of the experiment roadbed is in accord with the monitoring result

high quality and reliability of the settlement drill monitoring instrument had now been testified.
