摘要
通过试验,讨论温度、机速对轴向压裂法测定结果的影响及其规律,确定该法作为冻土抗拉强度间接测定方法的可行性。试验结果表明,测定值稳定,与温度和机速对应性良好,服从一定函数关系。通过修正,该法测定冻土抗拉强度是可行的,对现场原状冻土抗拉强度测定更具一定意义。
The paper discusses influence of temperature and machine speed on the results of theaxi al splitting test and its laws,and the possibili ty o f using axial splitting method toundirectly determine tensile strength of frozen soil through the test on saturated frozen loess。The test results show that obtained values of strength are stable,well related to the tempera-ture and machine speed and expressed in certain functions.The axial splitting test is reliablefor detemning tensile strength of frozen soil through correction。It is of value especially todetennine a tensile strength of undisturbed specimens in-situ.
