With soil body adopting the hyperbolic hardening model and cement-soil pile wall and anchors elastoplastic one

the influence of anchors’ diameter and length on the supportive structure has been calculated and analyzed. The results show

on the condition that the diameter reaches over 400 mm

such effects in the saturated soft clay as replacement

occupation and reinforcement are obvious; thus distinctively controlling the coping’s horizontal displacement and settlement of the soil mass behind the retaining wall; while less than 200 mm

all the functions vanish thus lowering the active reinforcement. As the anchor’s length arrives at 1.6 times as long as the excavation depth

the coping’s horizontal displacement and soil mass’s settlement behind the retaining wall would be under control in the efficient way

while exceeding that all the effects are not that clear. Compared to the monitoring data from the same foundation pit

calculated and measured values bear great repeatability and regularity.
