The shock-induced experiments for two typical rocks are done using planar impact technique on the one-stage light gas gun, and the ultrasonic tests in the damaged rocks have been measured by the use of the ultrasonic pulse-transmission method. The shock -induced damages of rock are related with the shock speed and the attenuation coeffcient of sonic wave, and the latter reflects the damage degree in rock fairly authentic. The attenuation coeffcient can be used as main damage parameter...

The shock-induced experiments for two typical rocks are done using planar impact technique on the one-stage light gas gun, and the ultrasonic tests in the damaged rocks have been measured by the use of the ultrasonic pulse-transmission method. The shock -induced damages of rock are related with the shock speed and the attenuation coeffcient of sonic wave, and the latter reflects the damage degree in rock fairly authentic. The attenuation coeffcient can be used as main damage parameter for constructing damage model of rock under dynandc loading.

在配有软回收装置的平板碰撞实验台上进行两种典型岩石冲击损伤实验,并对回收样品进行超声波测试,得知岩石的动态损伤与冲击速度和超声波衰减系数α有关,后者较好的反映了岩石的损伤程度。结果表明声波衰减系数α可作为表征岩石损伤模型的主要参量。

The dynamic damage properties of limestone are systematically studied through the one-stage light-gas(planar impact technique) and ultrasonic pulse-transmission method. The sound wave of the retrieved rock sample is measured and tested with the technique of ultrasonic wave measurement and test, the relation between attenuation coefficient and damage energy dissipation of the sample is established.

The dynamic damage properties of limestone are systematically studied through the one-stage light-gas(planar impact technique) and ultrasonic pulse-transmission method. The sound wave of the retrieved rock sample is measured and tested with the technique of ultrasonic wave measurement and test, the relation between attenuation coefficient and damage energy dissipation of the sample is established. Theoretical study and experiments show that in calculation, for the damage definition in this paper, damage parameter D=0.40 can be used to define the edge of fragmentation field of limestone. The experimental blast funnel is simulated with numerical method and the result shows that D=0.40 is feasible to be used to define the edge of fragmentation field.

利用一级轻气炮对灰岩进行冲击损伤实验,并对回收样品进行了超声波测试,在此基础上建立了衰减系数和损伤变量、冲击损伤耗散能的拟合关系式。将岩石高速冲击损伤实验所获得的损伤参数D=0.40作为破碎区的边界,对现场爆破漏斗实验进行了数值模拟,证明应用D=0.40作为破碎区边界完全可行。

With the increase of pile length,enlargement of pile diameter and the enhancement of pile bearing capacity,the dead-load pressed pile that was commonly used in the past to inspect the integrity and bearing capacity of pile is proved no longer effective,and besides the small strain at the pile foundation also makes it hard to be evaluated.This paper makes brief statement of using ultrasonic pulse transmission method to inspect the integrity of the cast-in-place pile in the pile foundation of Mahe Bridge...

随着灌注桩的桩长、桩径和桩的承载力的增大,过去常用静载压桩检验桩的完整性和承载力已很难实现,桩基小应变对于这样的灌注桩也难较好地进行评估。文章就店忠路马河桥桩基采用超声脉冲检验法检验灌注桩完整性作简要阐述。
