Foundation pit side wall displacement control method and system
The invention relates to a foundation pit side wall displacement control method and system, and the method comprises the steps: measuring the horizontal displacement of a foundation pit side wall supporting pile in a foundation pit depth range and the supporting axial force of the supporting pile in real time, and if the horizontal displacement or the supporting axial force exceeds a preset displacement alarm value, changing the supporting axial force borne by the supporting pile through increasing or unloading. Therefore, the horizontal displacement of the foundation pit side wall supporting pile and the supporting axial force are controlled to be within the alarm values all the time. According to the method and the system, a flexible horizontal displacement measuring device and a counter-force pushing device of the side wall of the foundation pit are combined together, the supporting axial force is regulated and controlled in real time according to the horizontal displacement situation and the supporting axial force situation of the foundation pit, the size and the distribution of the supporting axial force are dynamically adjusted, the horizontal displacement and the supporting axial force of a supporting structure are always within alarm values of the supporting structure, and the safety of the supporting structure is guaranteed. The limit value of the standard requirement is avoided, and the stability and safety of the side wall of the foundation pit are guaranteed.
本发明涉及一种基坑侧壁位移控制方法及系统，该方法包括实时测量基坑侧壁支护桩在基坑深度范围内的水平位移和支护桩的支撑轴力，若其水平位移或支撑轴力超过它们预设的位移报警值，通过增加或卸载改变支护桩所受支撑轴力，从而控制基坑侧壁支护桩水平位移及支撑轴力始终处于它们的报警值内。本发明方法及系统将基坑侧壁的柔性水平测位移装置和反力顶推装置结合在一起，通过基坑水平位移现状及支撑轴力现状实时调控支撑轴力，动态调整支撑轴力的大小和分布，使支护结构水平位移及支撑轴力始终处于它们的报警值内，避免超过规范要求的限值，保证基坑侧壁的稳定性和安全性。
