高压注浆土钉特性及应用
CHARACTERISTICS AND APPLICATIONS OF HIGH-PRESSURE GROUTING SOIL NAILING
【摘要】 面对重力注浆土钉的一些不足,提出了高压注浆土钉,并对它的一些特性作了一些探讨。通过土钉抗拔力学模型探讨了高压注浆土钉的抗拔荷载传递机理,简单介绍了其施工工艺。从土钉长度、抗拔安全系数、界面粘结强度、抗滑稳定性等方面说明了高压注浆土钉的优越性,并从实例分析证明其可行性。
【Abstract】 Aiming at the disadvantages of gravity grouting soil nailing,high-pressure grouting soil nailing is introduced in this paper,and its characteristics are discussed. Based on mechanics model of pullout,the transfer mechanism of pullout load of high-pressure grouting soil nailing is discussed. Moreover,the construction process is briefly presented. High-pressure grouting soil nailing has advantages in many aspects,including length of soil nailing,security coefficient of pull strength,bond strength of interface,stability against sliding. Its feasibility is proved in project example.
【Key words】 rock and soil mechanics; high-pressure grouting soil nailing; security coefficient; mechanics model; transfer mechanism;
