摘要:
介绍了吹填土真空预压工程中孔隙水压力计(以下简称“孔压计”)的传统钻孔埋设方法和改进埋设方法—插板机埋设,对使用改进埋设方法的监测数据进行了分析,并与钻孔埋设方法的监测数据进行比较。分析表明,采用插板机埋设的孔压计中产生明显超静孔隙水压力,且深部测点超静孔隙水压力消散所需时间较钻孔埋设的长;对于浅层深度的孔压计可采用插板机埋设,节省施工成本,方便快捷,而超过15 m深度的孔压计埋设则需采用常规钻孔。
Abstract:
This paper introduced two laying methods of pore water pressure gauge for vacuum preloading of dredger fill,i.e.traditional method of laying by drilling and an improved one of laying by spile machine,and compared monitoring data of the two methods.Results show that the gauge laid by spile machine will produce excess pore water pressure and the dissipation time of this pressure at deep measuring points is longer than that of pressure gauge laid by drilling.For pore water pressure gauge at shallow levels,using spile machine is convenient and cost-effective; while for pore water pressure gauge below 15m,traditional method of laying by drilling should be adopted.
