船闸在运行期间,由于地基、结构、水位和季节温度等各种因素对建筑物的影响,使船闸产生不同程度的垂直位移和水平位移,变化规律是复杂的。通过定期观测,可以掌握其变形规律,对验证设计数据,鉴定工程质量和确保工程安全很有意义。本文结合江苏省京杭运河施桥复线船闸施工期对一线船闸影响的监测,探讨在软土地基上进行变形观测的若干技术问题,提出观测的精度指标,观测方法及要求等。
Due to the influence of various factors such as foundation, structure, water level and seasonal temperature on the building during the operation of the ship lock, vertical and horizontal displacements of the ship lock are generated in varying degrees, and the variation rule is complicated. Through regular observation, we can grasp the deformation law, and it is very meaningful to verify the design data, identify the project quality and ensure the project safety. Based on the monitoring of the first-line shiplock during the construction period of the Shiqiao double-line shiplock of the Jinghang Canal in Jiangsu Province, this paper discusses some technical problems of the deformation observation on the soft soil foundation, and proposes the accuracy index, observation methods and requirements of the observation.
