Nowadays, soil nailing is widely used to stabilize slopes and excavations. The bond strength is integrated shear strength along the interface area between grout and soil. Choosing a value for bond resistance is one of the effective parameters in nailed wall design, which is generally determined by the values proposed by FHWA guidelines.
WebJun 22, 2024 · In the design of soil nail walls, the ultimate pullout resistance of a soil nail is often estimated by mobilizing the soil-nail interface shear strength over the entire bond area. This assumed uniform distribution of shear stress implies fully developed bond strength and a linear axial force profile over the embedment length. Web4.7 The soil nail must be installed in one operation and at a controlled rate to avoid damage to the nail and the drill hole. The nail must be inserted into the hole to the required depth …
