闸坝透水地基有压渗流计算方法,分为有限深及无限深地基两种,前者适用于地基深度T<0.5l_o,后者适用于T≥0.5l_o,这里T代表地面至不透水层面之距离,l_o代表地下轮廓线的水平投影长度。对于有限深地基的计算方法,常见的有H.H.巴甫洛夫斯基的分段法,C.H.努米罗夫的渐近线法,P.P.丘加也夫的阻力系数法。最近南京水利科学研究所毛昶熙、周保中在总结上述各法的基础上,特别是对丘加也夫的阻力系数法作了研究,提出
The calculation method for pressure seepage of the sluice foundation is divided into two kinds: finite depth and infinite depth foundation. The former applies to the foundation depth T<0.5l_o, and the latter applies to T≥0.5l_o, where T represents the distance from the ground to the impervious level. ,l_o represents the horizontal projection length of the underground contour. For the calculation method of finite deep foundations, the segmentation method of H.H. Pavlovsky, the asymptotic method of C.H.Numirov, and the resistance coefficient method of P.P. Chugakov are common. Recently, Mao Yongxi and Zhou Baozhong of the Nanjing Institute of Water Resources Science Research summarized the above methods, and in particular studied Qiujiafu’s resistance coefficient method.
