具体实施方式：
下面附图对本发明的技术方案做进一步说明。
 图1所示为一种用于相似实验模型的侧向加力装置的结构示意图。如图1所示，该装置由加力模块托架1和加力模块2组成；加力模块2置于所述加力模块托架2上，其中，加力模块2由上挡板21、下挡板22，加力弹簧23和限位卡扣24构成，上挡板21通过加力弹簧23与下挡板22连接，限位卡扣24安装在上挡板21和下挡板22两侧。
本发明使用方法和工作原理为：首先通过实际的水平构造应力，及其构造应力的梯度变化大小，选择合适的侧向加力模块2，选择好侧向加力模块后，调整加力模块内部的加力弹簧23，使所有加力模块的位移量相同并且能够达到实际要求的构造应力水平，然后锁紧限位卡扣24以保证模块不发生位移，接着浇注模型，待模型达到实际强度时，解除限位卡扣24，使其模块内部由限位卡扣24和加力弹簧组成的自平衡力转化为侧向水平构造应力施加于模型侧面，形成了模型的实际水平构造应力场。
