换土法 挖出地基中一定范围内的土后，换以砂、石等材料、并分层夯实（或压实、振实），以作为基础的持力层的地基处理方法，是传统的浅层处理地基的方法。置换后的土层称垫层。 垫层设计主要是选定垫层材料、确定垫层的宽度与厚度。垫层厚度应大于1/4基底宽度。 垫层宽度应能防止垫层材料侧向挤出，通常按应力扩散角设计，并超出基础底面边缘一定距离。同时应验算下卧层的容许承载力。 垫层按不同作用可采用砂、碎石、砾石、石屑、炉渣、素土或灰土。 砂石类垫层 用于处理厚度较薄的软土、冻土、杂填土或软硬不均的地基。这种垫层可减小地基的变形和提高承载力，并具有排水固结，加速建筑物的沉降和防止地基土冻胀等作用。 通常采用中砂、粗砂或砾石作为垫层材料。其含泥量不超过3％。施工时,可采用振动、水撼或碾压等方法使之密实。垫层的工程质量一般采用干容重测定或贯入法进行检验。 土（或灰土）垫层 在中国的西北和华北及湿陷?曰仆恋厍褂媒掀毡椋靡圆糠只蛉肯仆恋鼗氖荼湫危蛴靡蕴岣咴犹钔恋鼗某性亓Γ辉诮ㄖ锓段谏柚谜粒ɑ蚧彝粒┑娌闶被辜嬗辛己玫母羲饔谩? 施工时，土料要在最佳含水量下压实或夯实，并以干容重和压实系数控制质量。
