摘要
基坑内地基加固是确保深基坑安全稳定的重要措施之一。地基加固施工方法较多、加固的方式也不尽相同,其效果和价值也各不相同。文中通过对已建成的建(构)筑物下方土体加固技术的应用条件,分析了不同加固施工方法下加固效果,针对盾构后期下穿既有建(构)筑物的变形控制和保护要求进行基坑内土体加固方法。
Foundation reinforcement in foundation pit is one of the important measures to ensure the safety and stability of deep foundation pit.There are many construction methods for foundation reinforcement and different reinforcement methods,and their effects and values are also different.Through the application conditions of the soil reinforcement technology under the built building(structure),the reinforcement effect under different reinforcement construction methods is analyzed,and the deformation control and protection of the existing building(structure)is carried out in the late stage of the shield.The method of soil reinforcement in the foundation pit is required.
