前言为了建筑、结构物的安全,必须改良土质,如把土夯实。然而,传统的夯实方法仅限于人工和机械夯实技术,这对于大面积软土和较深层土质的高强度夯实显得十分不足。目前,爆破技术的飞速发展,利用强烈的爆炸冲击夯实土质,形成稳定、高强的承载工程地基,已具有经济、实用的意义。与国外的内部装药爆夯相比,本文提出的非接触装药爆夯中,浅层地基更有优越性,并相应提出了理论计算依据。
Introduction For the sake of the safety of buildings and structures, we must improve soil quality, such as consolidating the soil. However, traditional methods of compaction are limited to manual and mechanical compaction techniques, which are inadequate for high strength compaction of large areas of soft soil and deeper soil. At present, the rapid development of blasting technology, using strong explosive impact compaction of soil, forming a stable, high strength bearing foundation, has an economic and practical significance. Compared with foreign internal explosive explosive tamping, in the non-contact charge explosion ramification proposed in this paper, the superficial ground is more superior, and the theoretical basis is put forward correspondingly.
