软土固化地基轻型触探N10与静力触探qc相关性研究

Study on the Correlation between Light Penetration N10 and Static Penetration qc in Soft Soil Solidified Foundation

沼泽相软土使用ALLU搅拌头就地浅层固化后,利用静力触探手段进行检测固化土地基处理效果,现场不易操作。探究固化土轻型触探N10与静力触探qc之间的关系,利用精确度高的静力触探比对轻型触探锤击次数,由此建立就地固化土轻型触探N10锤击数与承载力之间相关性关系,然后使用平板静载荷试验验证数据地可靠性。取得当固化深度位于1.2 m时固化土轻型触探N10与静力触探qc之间的关系为:qc=-0.000 7N102+0.054 2N10+1.751。为工地试验室检测软土浅层就地固化地基承载力提供一种便捷的检测手段。

After the shallow surface of coastal soft soll solidifies on the spot,static sounding equipment is self-impirtant and the requirements for the detection environment are more stringent,given that the conical dynamic sounding test mechanism is similar to static sounding.To investigate the relationship between the light contact N10 and the reliability of the test data was verified by the plate load test using the high precision static contact ratio,and the correlation between the number of hammer strokes and the bearing capacity of the light contact N10 was established.If light contact N10 can be used instead of static contact qc,it can provide a convenient and quick method for the site laboratory to detect the treatment effect of shallow local curing soil roadbed.
