摘要

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。

Abstract

Offshore vane shear and penetration tests in situ were conducted in San Zao Bay near the pearl river mouth and systematic results of vane strength Cu and specific penetration resistance Ps were obtained. The specific penetration resistances and vane strength increase with the increase of depth

from which the formula

Cu = 0.0069h and Cu=0.0024Ps were derived. These conclusions provided the design bases for building the embankment in San Zao Bay. Also the method of offshore tests was improved according to the in-situ test conditions and a convenient and economical technique of offshore test for the similar engineering was given.
