in accordance with engineering practice, a new system for ground surface displacement monitoring system based on gis was established.
结合实际工程建立了基于g is的地表移动监测系统。
the lateral wall deflection is an important cause which results in ground surface displacement and settlement around an excavation.
深开挖工程中挡墻变形是引起基坑周围土体变形的重要因素之一。
together with the outcome existed, deduces the simplify equation of the ground surface displacement and deformation induced by the excavation in the free field;
结合已有研究结果,推导了基坑开挖引起的自由场地地表位移和变形简化计算公式;
