摘要
通过埋设在长江下游滩地软土中的原型观测仪器 ,对水上施打排水板、坡底铺设软体排、再用袋装砂吹填形成围堰以及后方陆域的围滩造地方法进行了监测和评估。结果表明 ,筑堰和吹填施工过程中地基是安全的 ,工程运行期软体排抛石护底区滩地稳定 。
By means of geotechnical prototype instruments installed in sotf soil,the forming land method is monitored and evaluated,in which the underwater ground below cofferdam is improed by wick drains,geofabric mattress is placed on riverbed and below bouleder apron,ground cofferdams is adopted sacked sand,the back land is fillde by dredging.The monitoring results indicate that the ground is safe during cofferdam construction and hydraulic fill,the apron area is stable during land operation,verifying the effectiveness of above forming land method and feasibility in deep water.
