【 摘 要 】

This research introduces the soil buildings' foundation of geological structure in Liaodong Peninsula and the building foundation type. It shows that there is a cosine changing of the distribution of the temperature field on an annual cycle, and a temperature changing lag exists for the different depth of foundation. Based on the law of frozen depth of foundation, the frozen procedures can be divided into four stages. Based on the observation data, the cathode surface temperature is positively correlated with both the frost heave quantity and the frozen depth. In addition, to reduce the observation cost and the measure difficulty, the frost heave quantity can be obtained through the observation of the frozen depth.
