摘　　要：河流阶地、河漫滩勘察过程中钻孔容易发生掉块、垮塌,严重影响了施工进度。首先,对该类地层发生复杂工况的原因进行了理论分析,明确了提高泥浆的黏度以增强孔壁粘结能力的思路。通过优选处理剂及其加量,确定了高效且环保的LG植物胶与XC为主剂,完成了针对性配方泥浆方案。现场实际应用过程中取得了良好的使用效果,可为其他类似工程提供一定的参考。During the survey of river terraces and floodplains,boreholes are prone to block drop and collapse,which seriously affects the construction progress.First of all,theoretical analysis of the reasons for the complicated working conditions of this type of formation was carried out,and the idea of increasing the viscosity of the mud to enhance the bonding ability of the hole wall was made clear.By optimizing the treatment agent and its added amount,the high-efficiency and environmentally friendly LG vegetable gum and XC were determined as the main agent,and the targeted formula mud scheme was completed.Good results have been achieved in the actual field application process,which can provide a certain reference for other similar projects.
