求翻译：随着基坑的开挖越来越深、面积越来越大，基坑围护结构的设计和施工越来越复杂，所需要的理论和技术越来越高，远远超越了作为施工辅助措施的范畴，施工单位没有足够的技术力量来解决复杂的基坑稳定、变形和环境保护问题，研究和设计单位的介入解决了基坑工程的理论计算和设计问题，由此逐步形成了一门独立的学科分支——基坑工程。 。是什么意思？

With the excavation of the pit deeper and deeper, the area is growing, more and more complex design and construction of the foundation pit structure, the theory and technology have increasingly high, far beyond as the construction of auxiliary the scope of the measures, the construction unit is not

As the pit dug deeper, and more and more in the pit, and the structure of the design and construction more and more complex, the need for more and more theories and techniques, and as far beyond the scope of the project measures to support construction units, there is not enough technology to solve

Excavates, the area more and more deeply along with the hole excavated for building foundation is more and more big, the hole excavated for building foundation surrounding protection structure design and the construction is more and more complex, needs the theory and the technology are more and more

As pit of excavation increasingly deep, and area increasingly large, pit enclosure structure of design and construction increasingly complex, by needs of theory and technology increasingly high, far beyond has as construction secondary measures of areas, construction units no enough of technology fo
