（ 2 ）將拱壩虛擬為由座落在壩基塊體有限元上的一系列懸臂梁與水平拱組成，將懸臂梁視作由水平拱所支承的彈性地基梁，考慮徑向和切向調整，比以往的彈性地基梁只考慮徑向調整有所發展；而且用塊體元模擬壩基，也能較精確地模擬壩基多種斷裂構造等對壩體結構行為的影響。 -
Construction of flat tunnel of large span at extra - shallow depth must be conducted on the principle that advance grouting should be strictly performed before excavation and length of pull at one time should be short, together with reinforced support, immediate closing and constant monitoring and surveying. that preceding pilot tunnels, large - volume excavation divided into small ones, excavation of flank before that of center, upper before lower, arch before wall etc is a good method which could effectively reduce surface subsidence and its adverse effect on adjacent buildings, in addition, some other measures are also taken to lessen blast - induced vibration in the ground and surrounding structures. in a word, all means and steps mentioned above have already proved effective and practicable in practice
軟弱大跨超淺埋扁平隧道必須按「管超前，嚴注漿，多分部、短開挖、強支護、快封閉，勤量測」的施工原則進行施工，採用「眼鏡超前，化大為小，先側后中，先上後下，先拱后墻」的施工方法控制地表沉降和對周邊建築物的影響；採用「多分部，化大為小，短進尺，密布眼，弱裝藥，設減振槽」 ，控制爆破振動，經過實踐證明，這些方法都是行之有效的。
