一、引言 深水抛填土作为防渗体,在水利工程中已经常使用。但已有的一些研究多侧重在抛填土的稳定边坡及渗透性方面。对水平防渗体(例为铺盖),由于铺盖的厚度远比垂直肪渗体的高度小,所以抛填土的抗渗强度及渗透性就成了主要问题。 深水中抛填粘性土及坝前的自然落淤都可形成水平防渗体。围堰、不清基筑坝以及

First, the introduction of deep-water throwing fill as impermeable body, water conservancy projects have been used often. However, some researches have focused on the stability of the slope and permeability of the tundish. For horizontal impermeable bodies (for example, bedding), the impermeable strength and permeability of the cast-in soil become a major problem since the thickness of the bedding is much less than the height of the vertical infiltrated body. Throwing clay in deep water and natural sedimentation in front of the dam can form a horizontal anti-seepage body. Cofferdam, unclear dam construction as well
