摘要
针对我国即将修建的京沪高速铁路,选取有代表性的粘性土填料,主要以无侧限抗压强度指标作为依据,研究开发出一种水泥系土壤固化剂,并通过大量室内试验,对固化剂改良土的强度和耐久性能进行了详细分析研究。在此基础上提出了固化剂改良土的施工特点及施工工艺流程,并指出固化剂进一步的研究开发工作。
According to the Beijing-Shanghai high-speed railway which will be built soon in China,typical cohesive soil filler is chosen to be researched for the development of cement-type soil curing agent on the basis of unconfined compressive strength index.Furthermore,the strength and durability of curing agent improved soil is analyzed in detail,based on which the construction characteristics and technology of curing agent improved soil are put forward.And the advanced research and development work is also indicated.
