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.
