1、检查强夯施工过程中的各项测试数据和施工记录,不符合设计要求时应补夯和采取其它有效措施。
1. Check the test data and construction records in the process of dynamic compaction construction. When they do not meet the design requirements, supplementary compaction and other effective measures should be taken.
2、强夯施工结束后应间隔一定时间方能对地基质量进行检验。对于碎石土和砂土地基,其间隔可取1~2周;低饱和度的粉土和黏性土地基可取2~4周。
2. After dynamic compaction, the quality of foundation should be checked at a certain interval. For gravel soil and sandy soil foundation, the interval can be 1-2 weeks; for silt and clay foundation with low saturation, it can be 2-4 weeks.
3、质量检验的方法,宜根据土性选用原位测试和室内土工试验。对于一般工程应采取两种或两种以上的方法进行检验;对于重要工程项目应增加检验项目,也可做现场大压板载荷试验。
3. The method of quality inspection should be in-situ test and indoor geotechnical test according to soil properties. For general engineering, two or more methods should be adopted for inspection; for important engineering projects, additional inspection items should be added, and large pressure plate load test can also be done on site.
4、质量检验的数量,应根据场地复杂程度和建筑的重要性确定。对于简单场地上的一般建筑物,每个建筑物地基的检验点不应少于3处;对于复杂场地或重要建筑物地基应增加检验点数。检验深度应不小于设计处理的深度。
4. The quantity of quality inspection should be determined according to the complexity of the site and the importance of the building. For general buildings on simple sites, there should be no fewer than three checkpoints for each building foundation; for complex sites or important building foundations, the number of checkpoints should be increased. Inspection depth should not be less than the depth of design treatment.
