本文介绍了近年来发展起来的一种新的土工测试技术——土工室内波速测试技术。同时较为详细地介绍了在土工室内波速测试中,所使用的三种不同形式的剪切波发射、接收装置。并采用室内剪切波波速测试的方法,研究了砂土、亚粘土的某些动力特性:应力状态与剪切模量的关系,孔隙水压力对剪切模量的影响。所得结果与用其它手段研究的结果是基本一致的。
This paper introduces a new geotechnical test technique developed in recent years - geotechnical indoor wave velocity testing technology. In the meantime, three different types of shear wave transmitting and receiving devices used in geotechnical indoor wave speed testing are introduced in detail. Some dynamic characteristics of sand and clay were studied by using shear wave velocity test. The relationship between stress state and shear modulus and the effect of pore water pressure on shear modulus were studied. The results obtained and other means of study is consistent with the results.
