The invention discloses a composite anti-seepage system suitable for an earth and rockfill dam on a soft foundation and a construction method of the composite anti-seepage system. A traffic corridor is arranged on a dam foundation of the earth and rockfill dam; the dam foundation diaphragm wall is arranged in the dam foundation and connected with a bottom plate of the traffic corridor. The anti-seepage core wall is arranged in a dam body of an earth and rockfill dam on the top of the traffic corridor and connected with a top plate of the traffic corridor. The anti-seepage core wall, the traffic corridor, the dam foundation anti-seepage wall and the anti-seepage curtain on the same longitudinal axis are tightly connected to form an earth and rockfill dam composite anti-seepage structure with a foundation riverbed as a deep covering layer soft foundation, and a good composite anti-seepage system is formed. According to the traffic corridor, an upper project and a lower project of the corridor can be developed at the same time, leakage safety monitoring is conducted in the traffic corridor, and grouting is conducted repeatedly when leakage occurs to ensure the anti-seepage effect of the whole reservoir dam; after a project is built, monitoring, management, repair and maintenance are facilitated, the management, operation and maintenance cost is reduced, and the method has the advantages of being convenient and safe to construct, short in construction period and remarkable in economic benefit.
本发明公开了一种适用于软基上土石坝的复合防渗系统及其施工方法，交通廊道设置在土石坝的坝基的上；坝基防渗墙设置在坝基的内部，并与交通廊道的底板连接；防渗心墙设置交通廊道顶部的土石坝的坝体内，并与交通廊道的顶板连接。本发明通过同一纵向轴线上的防渗心墙、交通廊道、坝基防渗墙和防渗帷幕紧密连接，组成适应基础河床为深厚覆盖层软基的土石坝复合防渗结构，形成良好的复合防渗系统。其中交通廊道使得廊道上下两部分工程可同时开展，在交通廊道内进行渗漏安全监测，出现渗漏时重复灌浆确保整个水库大坝的防渗效果；在工程建成后，便于监测、管理、维修和养护，降低管理运维成本，具有施工便利、安全、工期短和经济效益显著的特点。
