1) soil nailing stress
土钉应力
1.
The field test of the horizontal displacement of foundation pit wall with soil nailing and the soil nailing stress has been carried out.
通过对基坑复合土钉支护的坑壁水平位移和土钉应力现场测试,数据分析表明:土体最大水平位移发生于基坑顶部;基坑深度范围内中部土钉受力最大;土钉布置宜上长下短,下部土钉适当加密,以抵抗基坑底部存在的剪应力集中;重要区段基坑采用复合土钉支护,可提高基坑支护整体刚度,减小基坑变形,提高基坑安全度。
3) prestressed soil-nailing support
预应力土钉支护
1.
Under the condition of high water level and sand or silt as foundation soil,the typical experiences of multiple support technologies for underground projects of adjacent buildings are introduced,including high-pressure spiral pile waterproof curtain,precipitation,micro pile and prestressed soil-nailing support.
介绍了在地下水位较高、地基土层为粉土或砂土的情况下,邻接建筑地下工程如何将高压旋喷桩止水帷幕、井点降水、微型桩+预应力土钉支护技术综合使用的典型经验。
4) Composite prestressed soil nailing retaining
预应力复合土钉支护
6) prestressed composite soil nailing walls
预应力复合土钉墙
1.
According to the characteristics of the prestressed composite soil nailing walls,a new type of prediction deformation model is constructed——Verhulst model through analyzing the operation mechanism and influential factors during excavation and use of the walls,which is used to assess the deformation of prestressed composite soil nailing walls to provide effective evidence for the design.
针对预应力复合土钉墙的特点,通过分析其在基坑开挖、使用阶段的作用机理、影响因素,构建一种新型的预估变形模型——Verhulst预测模型用于预应力复合土钉墙变形估计,为设计提供有效依据。
