摘要
结合哈尔滨市某深基坑工程实例,从冻胀期与融化期两方面,监测了季冻区该深基坑桩锚支护体系的安全性,指出深基坑侧向水平位移在冻胀期与融化期均呈现复合式变形趋势,且变形趋势与大气温度变化趋势具有一致性和滞后性。
Combining with a deep foundation pit engineering in Harbin as an example,from the frost period and melting period two aspects,monitored the safety of support system of deep foundation pit anchor pile in seasonal frozen area,pointed out that the foundation pit side horizontal displacement all showed composite deformation trend in frost period and melting period,and the deformation trend and atmospheric temperature change trend had consistency and lagging.
