南京滁河漫滩软土性状研究
摘要:近年来,随着经济水平的不断发展,建筑物规模不断扩大,地下空间的开发利用逐渐引起重视。滁河漫滩区软土深厚,随着基坑规模的扩大,合理提供软土的物理力学参数将会在安全可靠的前提下节省大量的基坑围护费用,不仅能够产生经济上的效益,还能为建立完整的区域软土评价体系提供支持。对滁河漫滩区软弱土层性状进行多种手段对比分析,对原位测试经验公式进行修正,提供根据原位测试计算滁河漫滩区软土层承载力的方法,并对滁河漫滩区软土层在工程建设中的不利影响进行分析。
Abstract:With the continuous development of economic and building scale, it is more and more attractive to utilize the underground space. There is deep soft soil in floodplain of the Chuhe river. With the expansion of the scale of pit, reasonable physical and mechanical parameters will save costs for the pit protection in the promise of safety, which wiu be good for economic benefits and can offer support for establishing a complete evaluation system for regional soft soil. Analysis for properties of the floodplain soft soil and for adverse effects for the soft soil to construction is done. A modified formula for the in situ testing is proposed and thus a new method to calculate the capacity of the soft soil in floodplain with the in situ testing is suggested.
