满意答案
施工缝：因施工组织需要而在各施工单元分区间留设的缝。施工缝并不是一种真实存在的“缝”，它只是因后浇注混凝土超过初凝时间，而与先浇注的混凝土之间存在一个结合面，该结合面就称之为施工缝。
沉降缝：上部结构各部分之间，因层数差异较大，或使用荷重相差较大；或因地基压缩性差异较大，总之一句话，可能使地基发生不均匀沉降时，需要设缝将结构分为几部分，使其每一部分的沉降比较均匀，避免在结构中产生额外的应力，该缝即称之为“沉降缝”。
伸缩缝：若建筑物平面尺寸过长，因热胀冷缩的缘故，可能导致在结构中产生过大的温度应力，需在结构一定长度位置设缝将建筑分成几部分，该缝即为温度缝。对不同的结构体系，伸缩缝间的距离不同。
