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.

Key words: frozen soil, settlement, monitoring, instrument, development
