摘　　要：科学合理的设计理论是工程安全性和经济性的保障,现场监测是确保工程安全和质量最有效的手段。本文以提高刚性桩复合地基工程的安全性为目的,围绕关乎建筑物安全的"沉降量"等参数指标,从设计理论与试验监测两个方面开展研究。本文完善了刚性桩复合地基的设计理论,通过现场监测试验取得了第一手的数据资料,可作为今后类似工程的设计和施工参考。本研究为进一步提高刚性桩复合地基的安全性提供了理论和实践保障。The scientific and reasonable design theory is the security safeguard of the project; the engineering monitoring is the most effective method for ensuring the project security and its quality. The paper focuses on enhancing the security of rigid pile compound ground engineering as a goal, regarding concerns ＂the subsidence quantity＂ and so on parameter of the building security as targets. The above two aspects are studied in detail from the design theory and the experiment. The rigid pile compound ground design theory has been modified and improved in this paper. This paper has presented the useful first data information through the field tested experiment. The result may take as the design and the construction reference in the similar area and engineering. This research potentially provides the theory and the practice safeguard to further enhance the safety for the rigid pile compound ground.
