Abstract:

 On basis of the pull-out test results of the soil anchors in Shanghai area, the article analyzes on the distribution pattern of the axial forces, rebar stresses and lateral frictional resistance of the soil anchors installed in the saturated soft clays, discusses on the strengths of the rebars and grouting mortars that should be fully considered during the determination of the ultimate capacity of the soil anchors, and recommends a reference value for the lateral frictional resistance of the soil anchors in saturated soft clays similar to those in Shanghai area.
