一、引言:当地材料坝一般在坝体内设有粘土防渗心墙或斜墙,由于它要求有足够的密实度,往往很难选出合适的土料和不同的气象条件下的施工方法。特别是在潮湿多雨地区,土料的母岩风化形成多属于残积或坡积的粘性土,其物理力学性质与一般洪积或冲积的风化粘性土大有差异,同时又受到当地气象条件的影响,施工时的土料含水量和密实度就很难以控制。
I. INTRODUCTION: The local material dam is generally provided with a clay impervious core wall or inclined wall in the dam body. Because it requires sufficient densification, it is often difficult to select a suitable soil material and construction method under different weather conditions . Especially in humid and rainy areas, the parent material of the soil material weathered to form clay that is mostly residual or slope sediment. Its physical and mechanical properties are quite different from the weathering and cohesion soils of general alluvial or alluvial sediments, and are also affected by the local weather conditions , The construction of soil moisture content and density is very difficult to control.
