现场的测验作业是强夯施工的一个重要组成部分。为此，在大面积施工之前应挑选面积不小于400㎡的场所进行现场实验，以便获得规划数据。测验作业一般有以下几个方面内容：
On-site testing is an important part of dynamic compaction construction. Therefore, before large-scale construction, site experiments should be carried out at sites with an area of not less than 400_in order to obtain planning data. Test assignments generally have the following aspects:
1、地上及深层变形。地上变形研讨的意图是：
1. Overground and deep deformation. The purpose of the above ground deformation study is:
（1）了解地表拱起的影响规模及垫层的密实度改变；
(1) Understanding the influence scale of surface arching and the change of cushion compactness;
（2）研讨强夯夯击能与夯沉量的联系，用以确认单点最佳夯击能量；
(2) Discuss the relationship between dynamic compaction energy and compaction settlement, in order to confirm the best single-point compaction energy;
（3）确认场所均匀沉降和搭夯的夯沉量，用以研讨强夯的加固效果。
(3) To confirm the uniform settlement of the site and the compaction settlement of tamping, so as to study the reinforcement effect of dynamic compaction.
变形研讨的手法是：地上沉降观测、深层沉降观测和水平位移观测。
The methods of deformation research are ground settlement observation, deep settlement observation and horizontal displacement observation.
