摘要
通过对珠海西区沿海一带软土层的应力历史进行分析,论证了此类软土层欠固结状态产生的原因,应用考虑软土应力历史的固结沉降计算方法,对该区软土层固结沉降周期及沉降量进行了初步估算,并对其在工程建设中产生的灾害形式进行阐述和分析,结合近年当地工程建设经验,针对软土层的固结沉降对建(构)筑物的影响提出了相应的工程防治措施。
Through analysis of stress history of soft soil layers located in coastal areas in western district of Zhuhai,the cause of underconsolidation state of this layers was verified.Using consolidation settlement calculation method which can take into account of stress history of soft soil,the consolidation period and consolidation value of soft soil layers was preliminarily estimated.Disaster styles brought up by consolidation settlement during engineering construction was described and analyzed.With the help of engineering construction experience of recent years from this district,effective measures was put out to protect buildings and structures from influence of consolidation settlement of soft soil layers.
