摘　　要：昆明地区紧邻滇池流域,高原湖相沉积软土分布广泛,在这些地区从事工程建设时,须对这些软弱土层进行处理,以满足地基承载力要求和减少工后沉降。本文根据昆明某软土地基沉降曲线来推算土体的固结参数及固结度。通过对比分析推算值与理论值发现,基于实测数据推算的固结度介于理想井计算值与非理想井计算值之间,并提出了高原湖相沉积软土的固结参数β的建议取值范围,为此类地区软土地基处理提供了参考。Kunming area is adjacent to dianchi, and soft soil of plateau lacustrine-deposits is widely distributed. When we are engaged in engineering construction in these area, we should deal with these soft ground, in order to meet its foundation bearing capacity and reduce post-construction settlement. In this paper, it is studied by using settlement-time curves of soft ground in Kunming to predict consolidation parameters and degree of consolidation. Through the comparison of the calculated value and the theoretical value, it is found that the degree of consolidation predicted which is based on the measured data is between the value of ideal wells and non-ideals. Meanwhile, this paper points out the range of consolidation parameters of soft soil of plateau lacustrine-deposits. It provide the the reference for foundation treatment in plateau lacustrine-deposits.
