软土地区临近既有建筑物的深基坑支护设计

Design and Construction of Soft Deep Foundation in Soft Clay Regions Near Existing Buildings

简要介绍了某软土地区深基坑现场采用传统被动区加固和新型结构化加固试验的研究成果,内容包括所采用的试验方法和主要的试验结果,在传统被动区加固试验结果的基础上,指导改进为新型结构化加固,使被动区加固更合理,通过对基坑支护桩后土体的土压力进行测量。研究结果表明,在相同的加固效果的作用下,新型结构化加固可以充分的利用结构化体系而达到节省材料用量的目的。

A brief introduction of a deep pit in soft soil site using traditional passive zone reinforcement and structural reinforcement of new research trials,including test methods and test results mainly used in the traditional passive zone on the basis of the test results reinforced,improved guidance for the new structure of the reinforcement,reinforcement is more reasonable to make passive zone,through the excavation of soil behind piles of earth pressure was measured,the results show that under the action of the same reinforcing effect of the new structure of the reinforcement can be fully the use of a structured system to achieve the goal of saving the amount of material.
