采用压浆法控制地面沉降和提高挡土墙强度工程实践

Engineering Practice of Pressure Grouting for Control on Land Subsidence and Improving the Strength of Retaining Wall

摘要:

通过用压浆法对核力机械股份有限公司厂房内、外的地面沉降、开裂和挡土墙裂缝进行控制性治理之工程实践，阐述了在土层结构复杂、性状不稳定等情况下，在制定方案、参数选择和工程实施过程中，应把施工经验、理论计算、试验资料和工程实际进行综合分析，及时调整设计和施工方案，保证安全，确保工程质量。在分析地面沉降、开裂和挡土墙裂缝产生的原因基础上，提出了治理方案，并详细介绍了治理方案实施过程中的技术措施。

Abstract:

Based on the engineering practice of pressure grouting for control on land subsidence and crack in and out of a workshop and the crack in retaining wall, this paper suggested that comprehensive analysis should be made on construction experience, theoretical calculation, testing data and field engineering for scheme establishing, parameter selection and engineering construction. Treatment scheme was put forward and the technical measures were detailed.
