【摘要】

：

基于陆浑水库东湾站1960-2013年实测汛期径流资料及1975-2013年汛期降雨资料,采用变差系数、径流系数、M-K非参数检验法以及滑动t检验法等方法分析陆浑水库汛期入库径流、降雨的年际变化、突变变化的规律和变化趋势.结果表明:径流及降雨的年际变差系数较小,没有明显的突变;径流系数的年际变化不稳定;该流域汛期径流量和降雨量均呈现明显的下降趋势,具有一定的持续性.

污染场地修复药剂对高压旋喷装置的腐蚀及注人工艺的试验研究

采用传统的注入井注射药剂进行土壤修复时,修复效果差且治理周期长.本文采用高压旋喷注浆技术来弥补传统药剂注入方式的不足.进行室内浸泡试验,研究对比传统修复药剂对高压旋喷设备的腐蚀性;同时采用水泥浆液作为"药剂"进行高压旋喷的现场模拟试验,得到了适用于上海粘性地层中的土壤原位修复高压旋喷工艺参数,完善了适用于污染场地原位修复的旋喷工艺.
