tufong k0IWo土方开挖(earth exeavation)为工程建设将土(包括猫性土、砂土、砾、卵石及特大块石等)开采并从一处搬运至另一处的施工过程。水电工程的土方开挖包括弃土和取土。 (1)弃土是将建筑物多余土方开挖、运输、堆里在弃料场的施工过程。常用于场地平整、基础土方开挖、河道疏浚及地下工程中的土方掘进等工程。 (2)取土是在指定料场开采土料运至指定地点的施工过程。常用于天然骨料开采、土坝坝料开采、建筑物回填料等工序。尽量利用弃土做好土方平衡，是水电建设中节约资金的主要措施之一。 土方开挖根据施工条件分为陆上、水下和特殊施工3种。 陆上施工水位以上的各类土方开挖。水电工程土方开挖量大，一般都采用机械作业。机械作业在土层较厚、土壤天然含水量较低时，常用正、反铲挖掘机、斗轮回转挖掘机等立面开挖，自卸汽车、带式输送机运输。土层较薄、土壤天然含水量较高、施工场面宽大时，常用铲运机、推土机配装载机平面开挖，自卸汽车运输。坝料开采应在设计选定的料场进行。料场开采前应先清除无用覆盖层及树根、乱石等废弃物，选择合适的开采方案并根据开采运输条件和天气等因素，经常观测料场含水量的变化，并采取相应措施作适当调整以满足筑坝要求。在高边坡开挖时，要根据不同土质保持边坡稳定或及时支护以策安全。 水下施工包括砂砾料开采和特殊部位淤泥清除等。水下砂砾料开采包括天然骨料开采和坝料开采两种。特殊部位淤泥清除，如围堰过水后的基坑清淤，围堰堰体水下部分拆除等。常用的水下土方开挖机械.有索铲，正、反铲，抓斗，挖泥船和采砂船等。 特殊施工在工程特殊部位采用特殊手段的施工方法。主要有:①用风水枪配泥浆泵清除淤泥。②用高压水枪将土造成泥浆利用地形高差自流输泥至需用部位的水力冲填。③隧洞的盾构法、顶管法等(见隧洞开挖)。④在流沙地层开挖地下工程时的冻结法，即将周围土壤冰冻的开挖方法。
