本文通过室内模型试验,测得在波浪作用下杜洛斯块体在两种受力条件(安放形式)下所承受的波压力,通过分析计算,求得其肢杆和腰肢两断面处所承受的弯应力,以素混凝土的抗拉强度作为衡量标准,分析其在肢杆和腰肢两断面处发生开裂的可能性,得到杜洛斯块体的开裂与否和其受力条件或安放形式关系甚大,如安放不当使共处在最坏的受力条件下,则当杜洛斯块体的单块重量大于4.774吨(或波高大于5.36米)时,块体就有发生开裂的可能,如果安放妥当,则当杜洛斯块体的单块重量要大于198.2吨(或波高大于18.56米)时,块体才有发生开裂的可能。
In this paper, the wave pressure of the Duros block under two kinds of stress conditions (placed in form) under the action of waves is measured through the indoor model test. Through analysis and calculation, the pressure suffered by the limbs and the waist and limbs Bending stress is based on the tensile strength of plain concrete, and the possibility of cracking occurs on the two sections of limb and waist. It is found that there is a great relationship between the cracking of the Duros block and its stress conditions or placement If improperly placed to coexist under the worst conditions of stress, then when the monolith block weight greater than 4.774 tons (or wave height greater than 5.36 meters), the block has the possibility of cracking, if properly placed, When the monolith block weight is greater than 198.2 tons (or wave height greater than 18.56 meters), the block was the possibility of cracking.
