The paper provides the key factors to control the pit construction by restricting heave of the bottomsoil and minimizing tunnel displacement.
文章阐述了如何通过控制基坑施工主要影响参数，进而限制坑底土体隆起，减小隧道位移。

Results show that exposure time of pit bottomsoil affects notably the diaphragm wall displacement during the periods of both soil exposure and pit bottom construction.
本文就坑底土层局部加固对支护结构位移的影响效果和规律，结合工程实例，并从理论上进行了分析研究。
