GS新型固化剂加固滨海软土地层试验研究

Experimental Study on GS New Hardener for Strengthening Coastal Soft Soil

固化剂加固软土可以使软土满足工程建设要求,其具有高性价比,无毒、无公害等优点。在对滨海地区进行软土地基加固处理时,采取现场调查研究、理论分析、室内试验等多种途径,根据室内试验得出的结果,得出以软土在使用加固剂加固软土前后其强度变化规律,得出影响软土在加固后的无侧限抗压强度值的因素。通过控制变量的方法,对固化剂掺入比以及养护龄期这两方面进行研究,结果显示新型固化剂的掺入量对软土的加固效果影响较大,而加固后的养护龄期对其影响却不是那么明显。采用对比试验,得出新型加固剂加固效果更明显。

Curing agent with high cost-performance,non-toxic,non-pollution and other advantages,which can make soft soil meet the requirements of engineering construction.In the reinforcement of soft soil foundation in the coastal area,field investigation,theoretical analysis,indoor test and other methods are adopted,according to the results of laboratory tests,the strength variation of soft soil was observed before and after the use of reinforcement,and the factors affecting the unconfined compressive strength of soft soil after reinforcement are analyzed.In order to study the strength change rule of soft soil after reinforcement,the incorporation ratio of curing agent and curing age were studied by using the method of controlling variable,the results show that the incorporation of new curing agent has a great influence on the reinforcement effect of soft soil,but the effect of curing age is not so obvious.By contrast test,we set the soft soil strengthened by traditional cement and the soft soil strengthened by new type of reinforcement agent as the control experiment,through contrast,we can get the new type of reinforcement agent reinforcement effect is more obvious.
