某人工填土场地北侧采用二级挡土墙进行护坡,在场地上修建的多幢建筑物完工之后,施工方发现一级片石挡土墙、二级混凝土轻型挡墙及其承台梁产生多条裂缝。后经现场踏勘、设计图纸分析,对挡墙提出了护坡加固方案,并采用经典土压力理论对桩、墙进行理论分析计算。研究表明:加固后,桩、承台梁及挡土墙作为一个整体,其抗滑移能力,抗剪能力及抗倾覆能力均满足要求。经过一年的使用情况看,当时提出的简易护坡方案是合理的,达到了经济、实用的目的。 A second class retaining wall is used for slope protection on the north side of an artificial filling site. After the construction of several buildings completed on the site, the construction side finds that a grade of stone retaining wall, a secondary concrete lightweight retaining wall and its supporting platform beam generate more Cracks. After on-site survey and design drawings analysis, a plan for slope protection was proposed for the retaining wall, and the theoretical analysis and calculation of the pile and the wall were carried out using the classical theory of earth pressure. The research shows that the pile, the platform girder and the retaining wall, as a whole, meet the requirements of anti-skidding, anti-skidding and anti-overturning after reinforcement. After a year of use, the simple slope protection plan proposed at that time was reasonable and achieved economic and practical purposes.
