| 摘 要： | 在室内试验模型槽内构筑模型地基,在不同的土层温度下打设湿喷桩。在桩底预埋土压力盒测量桩端应力,并在28d龄期进行载荷试验,得到不同养护温度、不同土层下的桩体强度指标。提出土层温度越高,单桩的承载力越大,桩体的压缩量越小,桩顶的沉降越小;不同的养护温度造成了不同的桩端应力增长速度和桩侧摩阻力增长速度。

| Abstract: | Model foundation is built in model shafts of laboratory test tank and WJP is drived in different soil horizons temperature.Burying earth pressure cell under the base of WJP to measure pile end stress,and doing the loading test in 28d,pile strength indexes in different conservation temperature and soil horizon can be obtained.If soil horizon temperature is higher than before,pile capacity will be more strong,pile compression and the settlement of pile top will be smaller;different conservation temperatures will cause different growth rate of pile tip stress and pile side frictional resistance. |

| Keywords: | WJP soil horizon temperature bearing capacity settlement |
