摘要：

In order to analyze the applicability of the pile-anchor retaining structure in soft soil foundation, combined with some examples of foundation pit engineering in Lianyungang area, the deformation characteristics of pile-anchor was analyzed and think anchorage angle has a greater impact on supporting effect, so the numerical model was established to calculate the influence of different anchorage angle to pit's deformation, the results show: there is a different from rock slope anchorage, foundation pit of soft ground has not the optimal anchorage angle, but anchorage angle is bigger, the better. In addition, the foundation pit in soft soil, the pile-anchor structure is prone to rotate, which exacerbated the deformation of the soil. This kind of phenomenon will be intensified, when the anchorage Angle is larger, when the anchorage angle reaches a certain value, the pile bottom even has a reverse displacement.
