摘要

变形监测是岩土工程的重要组成部分，但大量常温工作环境下的岩土工程监测设备在面对低温环境时，将会遇到较非冻结区更为复杂的问题，其性能也将大打折扣。结合冻土区变形监测的特殊性，吸取数码监测、光纤传输的优点，研制了冻土变形钻孔沉降监测装置，详细介绍了该装置的原理和实施方式，并将其运用到青藏铁路试验路堤的现场监测中。结果显示该设备操作简单方便、监测结果可靠，精度满足科研、工程要求，可在冻土工程中运用。

Abstract

Settlement monitoring is an important aspect of geotechnical engineering. A lot of settlement monitoring instruments which work in normal temperature circumstance

will confront complex questions when they face low temperature circumstance; and their performance will also play down greatly. So we developed a drill monitoring instrument for frozen soil settlement in consideration of the particularity in low temperature circumstance. The instrument utilized advanced technology of numerical code monitoring and optical fibre transmission. Principle and practice of the equipment have been detailedly introduced. We carried out the embankment filling grading and reconstructing local experiment

inbuilt the frozen soil settlement drill monitoring instrument to monitor the settlement of the frozen soil. Result shows the settlement drill monitoring instrument has high quality and reliability and is worthy of popularization and application for the strongpoint of direct-viewing and convenient manipulation.
