本文介绍在珠江口三灶湾水上进行的十字板剪切和静力触探试验,获得了室内试验未能得到的土的十字板强度 C_u 和比贯入阻力 P_s 随深度增加而增大的有规律的结果。由这些试验结果,获得了两个近似公式 C_u=0.0069h 和 C_u≈0.024P_s,为筑堤提供了设计依据。另外,根据现场试验条件,因地制宜,采用简易的水上试验方法,为类似工程提供了方便和经济的离岸试验技术。
This paper describes the cross-plate shear and cone penetration tests conducted on the Sanzao Bay water of the Pearl River Estuary. The cross-plate strength C_u and the specific penetration resistance P_s of the soil that could not be obtained in the indoor test have been increased with increasing depth. Regular results. From these experimental results, two approximate formulae C_u=0.0069h and C_u≈0.024P_s were obtained, which provided a design basis for embankment construction. In addition, according to the field test conditions, local conditions, the use of simple water test methods, to provide a convenient and economical offshore test technology for similar projects.
