摘要:
针对城市顶管施工对邻近建筑沉降预测精度不足的问题，本文提出一种结合有限元与响应面法的沉降预测模型。以宁夏银川某装配式沉井和顶管电力隧道工程为依托，构建三维有限元模型模拟施工全过程，并基于实测数据对有限元模型进行了验证：装配式沉井施工对建筑物沉降影响小于0.8%；顶管施工沉降的有限元预测误差低于5%。通过单因素分析，明确了X向距离、Y向距离、顶推力及注浆压力对沉降的影响规律。基于Box-Behnken试验设计建立预测方程，确定系数R?达0.9989，F检验失效概率小于0.0001。应用该方程对JD7~JD13测点进行预测，平均误差为3.92%。模型应用于云端平台，有效提升了施工安全性。
Abstract:
To address the issue low prediction accuracy of adjacent building settlement caused by urban pipe jacking construction, this paper proposes a settlement prediction model that integrates the finite element method (FEM) and the response surface method (RSM). Based on a prefabricated caisson and pipe jacking power tunnel project in Yinchuan, Ningxia, a three-dimensional finite element model was established to simulate the entire construction process, and field monitoring data were adopted to validate the model. The result shows that the impact of prefabricated caisson construction on building settlement is less than 0.8%, and the FEM prediction error for pipe jacking-induced settlement is below 5%. Through single-factor analysis, the influence laws of X-direction offset, Y-direction offset, jacking force, and grouting pressure on settlement were clarified. A prediction equation was established based on the Box-Behnken experimental design, with a coefficient of determination R?reaching 0.9989 and the F-test significance probability lower than 0.0001. The average prediction error for monitoring points JD7-JD13 is 3.92%. Deploying the proposed model on a cloud platform effectively improves construction safety.
