摘　　要：主要对浮体系泊锚碇进行系统研究,并侧重对新近出现的大重量砼锚碇块的稳定和系住力进行探讨。建议其锚碇力仍采用原近似计算公式,其中锚的抓力系数可按本研究推荐采用的按锚碇块不同施工方法及埋置深度而异的抓力系数.锚链不同仰角θ对锚抓力系数的影响按所附实验曲线查取.波浪的动力影响,由于资料有限尚不足以给出定量值而只能定性描述.今后应加强成功经验的积累和出事现场的调查分析,推荐公式各系数的应用值仍应采用对比研究为主.This paper mainly describes the systematic research on floating body anchorage,particularly on the stability and anchoring force of emerged recently heavy concrete anchor block.It is proposed the existing approximate formula be used to calculate the anchoring force, and theholding force coefficient of anchor be determined according to the construction manner of theanchor block and its embedded depth. The holding force coefficient of anchor varies with differentangles of elevation of the anchoring chain, which can be valued through the enclosed experimentalcurve. Only qualitative description of wave dynamic effecti can be given instead of quantitativeanalysis due to shortage of data. It is suggested accumulation of experience of both success andfailure be enhanced, and the coefficients of proposed formula be determined via comparativeresearch.
