| 摘 要： | 通过观察挡墙变形裂缝和分析测量数据，对大面积堆载引起的地基不均匀沉降的原因进行了阐述，指出填土地基在压实处理时的不均匀性，造成局部地基强度偏低，雨季地表水体下渗，降低了土体强度是引起挡墙局部不均匀沉降的主要原因。根据实际情况，提出了立即封闭地表，减少水体下渗，适当增加挖孔桩配筋量，建立观测网、实施有效监测的处理措施。

| Abstract: | Based on the study of the retaining wall fissures and measurement data,the author expounds the reason of foundation uneven settlement by regional loading.Some parts of foundation's strength are on the low side and the rainfall infiltration decreases the soil strength is mainly caused the uneven settlement.The active suggestions of construction have been put forward,for example,to seal ground surface,to increase reinforcing bar in cast in place piles to build monitoring system. |
