GW001 日本学者主张发展“耐水性”堤防河川堤防的检验一向均以浸润线和防漏措施为重点,至于降雨从堤顶和边坡表面渗入堤体影响堤防安全的评价方法研究不深。日本有关人员经过多方面的比较研究后,认为除了个别特殊情况下,应大力提倡能防止降雨向堤体渗透的所谓“耐水性’堤防。这种堤防只保持 GW001 Japanese scholars advocate the development of “water resistance” embankment River embankment inspection has always been to infiltration lines and leak prevention measures as the focus, as the rainfall from the embankment and slope surface dike impact embankment safety evaluation method is not deep. After many comparative studies conducted by Japanese officials, it is believed that except for some special cases, so-called “water-resistant” embankments that prevent the infiltration of rainfall into the dike should be advocated vigorously.
