Anti-seismic structure for reducing earthquake displacement of earth and rockfill dam foundation and construction method
The invention discloses an anti-seismic structure for reducing earthquake displacement of an earth and rockfill dam foundation and a construction method. The anti-seismic structure comprises a dam body and the dam foundation. An anti-seepage body is arranged on the upstream side of the dam body, a supporting body is arranged on the downstream side of the anti-seepage body, and the anti-seepage dam is characterized in that plastic concrete or low-grade concrete with the thickness of 20-30 cm is arranged at the position, corresponding to the supporting body of the anti-seepage body, of the dam foundation, and the bottom of the supporting body is embedded into the plastic concrete or the low-grade concrete. The supporting body and the dam foundation are connected together through the plastic concrete or the low-grade concrete, and a contact zone with the corresponding thickness and roughness is formed. By means of special treatment measures on the contact face of the dam foundation and the filling earth and stone materials, deformation of an anti-seepage body and a joint can be effectively limited when an earthquake occurs, and the problems that reliable structural anti-seismic measures for controlling earthquake displacement are lacked between the dam foundation and the dam body filling materials in the engineering field and the like are well solved.
本发明公开了一种减小土石坝坝基地震位移的抗震结构及施工方法，包括坝体和坝基；坝体的上游侧设置防渗体，防渗体的下游侧为支撑体，其特征在于所述坝基的对应防渗体的支撑体位置设置20～30cm厚的塑性混凝土或低标号混凝土，所述支撑体的底部嵌入到所述塑性混凝土或低标号混凝土中，通过所述塑性混凝土或低标号混凝土将支撑体与坝基连接在一起，形成具有相应厚度和粗糙度的接触带。本发明通过对坝基与填筑土石料接触面的特殊处理措施，可有效限制发生地震时防渗体及接缝变形，较好解决工程界对于坝基与坝体填筑料之间缺少可靠的结构抗震措施控制地震位移等问题。
