摘要
在分析传统冻土器结构缺陷的基础上,通过一系列改进试验,以一种新的试验设备和采样方法获取冻土深度资料,与外界实际观测到的土壤冻结情况有较好的响应。对比分析传统冻土采样资料,结果表明:不同深度冻土资料的分布,新、旧两种方法所获取的数据表现出很大的差异性。传统冻土器结构、采样方法表现出显著的缺陷和不足:响应差,漏采样严重;新方法所获取的冻土深度数据与最低温度及低温下的风速、时温累积等表现出较好的相关。本文阐述的试验方法和结果为改进传统冻土仪器提供了一定的技术依据。
Based on the analysis of structural defects of traditional frozen soil equipment,the frozen soil depth is preferable to practical observation by the new test equipment with new sampling method.According to comparative analysis of sampling data,the results show that the data distribution of frozen soil in different depth acquired by the new and old equipment is quite different.The traditional frozen soil equipment and sampling method have obvious disadvantages,such as poor response and big loss of sampling.However,the frozen soil depth acquired by the new method has better correlation with minimum temperature,sum of hourly negative temperature and wind speed in low temperature.Furthermore,the test methods and results described in this paper can provide technical basis for improving the traditional frozen soil equipment.
