湛江一区码头在施工及运用期间持续发生位移,至1981年,最大水平位移已达512毫米。由于现场只测量了码头表面的位移与沉降,这些资料并不能说明码头的实际工作状态和位移原因。所以,近年来就着手从地基土的基本特性进行研究。研究表明,湛江粘土是一种高孔隙比灵敏粘土,在天然状态下具有很好的力学特性,在受到扰动后,土的力学特性急剧恶化。由于土的逐渐破损,会使其由峰值强度逐渐降低到残余强度。此外,本文还从土—结构物的相互作用,来对码头位移的原因进行探讨。
The wharf in Zhanjiang District 1 was continuously displaced during construction and operation. By 1981, the maximum horizontal displacement had reached 512 mm. Since the site only measured the displacement and settlement of the wharf surface, these data could not explain the actual working conditions and displacement causes of the wharf. Therefore, in recent years, we have begun to study the basic characteristics of the ground soil. Studies have shown that Zhanjiang clay is a clay with high porosity ratio and has good mechanical properties under natural conditions. After being disturbed, the mechanical properties of soil deteriorate rapidly. As the soil gradually breaks, it will gradually decrease from the peak strength to the residual strength. In addition, the reason of the displacement of the wharf is also discussed from the interaction of soil and structure.
