摘要
根据对复合土钉墙支护机理的研究,提出采用单排或双排水泥土桩形成帷幕后再施作土钉支护,以解决边坡挡墙的隔水,防渗及临时自稳能力;提出相应的设计计算模式;总结了与软土地层相适应的施工工艺,汇总了近两年来在上海软土中土钉的应用情况,井对应用前景进行了分析。
To use the soil-nailing in the soft ground,the ground water sealing must be established,and slope must be self stabilized . A technology which setting up cement-soil mixing pile at first,and then constructing the soil nailing support is put forward. By studying the principle of the compound soil-nailed wall, the design model is proposed . The construction technology suited to the soft ground is summarized.
