Small-radius curve shield tunneling thrust self-adaptive prediction method

The invention discloses a small-radius curve shield tunneling thrust self-adaptive prediction method, and belongs to the technical field of tunnel shield construction. The method comprises the following steps: pre-inputting geological data, a planning path curve and shield machine data, and predicting the shield tunneling thrust of the small-radius curve, including calculation of attitude adjusting moment, calculation of total thrust considering shield turning and attitude adjusting effects, and load distribution of a jack of a propelling system. A small-radius curve shield tunneling thrust self-adaptive prediction method is adopted to determine shield thrust to adjust the posture of a shield tunneling machine, and compared with traditional shield posture adjustment based on artificial experience, the shield posture adjustment method can effectively adjust the shield posture, so that segment damage, route deviation and potential operation problems are reduced. 一种小半径曲线盾构掘进推力自适应预测方法，属于隧道盾构施工技术领域。所述方法为：通过地质资料、规划
