為模擬於淺覆蓋或偏壓之節理地層中,因隧道開挖所引起的工程災害,本研究採用落門試驗進行單、雙孔隧道開挖引致地表沉陷與地層變動特性之探討,並利用近景攝影測量技術做為量測工具,探討隧道開挖後,地表之沉陷變形與隧道頂拱上方整體岩體變動的影響範圍,再利用數值模擬進行試驗結果驗證與比較。
試驗結果顯示在淺覆蓋水平地表之單隧道開挖中,地表沉陷以節理角度45°時之影響範圍最大,影響範圍為3.5D;地層變動特性中,節理角度0°、30°之拱效應影響區高度分別為0.5D與0.25D,節理角度45°、60°則無拱效應影響區產生;在雙孔隧道開挖中,以兩隧道間距S=0.0D對於地表沉陷量與地層變動的影響最為明顯,而兩隧道間距為S=1.0D時進行開挖,無相互干擾的情況且呈現各自獨立之狀態,在此條件下兩隧道頂拱上方皆會有一鬆弛區產生,其高度為0.5D,另外以隧道間距為0.5D時,左側新開挖隧道所產生的鬆弛區高度會小於右側既存隧道開挖後所產生的鬆弛區。在此逆向坡偏壓地層存在不同節理角度下進行隧道開挖,地層的影響範圍會隨隧道位置與節理角度的不同而有所影響,當隧道位置所處覆土平均高度越高時,則所產生的影響範圍也相對較廣;當地層節理角度越大,對於地層整體地層變動影響範圍越大,對水平地表面的影響也相對越廣。而數值模擬結果顯示,DDA小變位之模擬與試驗結果相比較則有高估的情況產生,其於階段之模擬皆有良好的模擬狀況;Phase2之模擬成果以節理角度60°為例,與試驗結果比較在開挖量為δ=2、4mm時,有良好的模擬成果,達最大開挖量時,則會有低估的情況發生。
In order to simulate construction-related hazards caused by tunnel-digging in shallow-covered or unsymmetry joint formations, in this study the trapdoor test was adopted to discuss the characteristics of the sinking and formation-changes caused by the digging of single or twin tunnels. Close-range photo-grammetry was also utilized as a measurement tool to examine the scope of the changes in the sinking and the rocks above the arch of the tunnel after digging begins. A numerical simulation was then carried out to test and compare the results.
The test result indicates that the scope of influences is at its largest, being 3.5D, when the sinking is at a joint angle of 45° in the digging of a single-tunnel in a shallow-covered terrain. Of the characteristics of formation changes, the heights of the arching effect’s influence zone are respectively 05D and 0.25D when the joint angles are 0° and 30°; no arching effect takes place when the joint angles are 45° and 60°.In the case of the digging of a twin-tunnel, influences on the degree of sinking and formation changes are most significant when the distance between the twin channels is S=0.0D. If the diggings of the twin channels took place when the distance is S=1.0D, did not interfere with each other, and were independent from each other, a disturbed zone each would occur above the arches of the twin channels at the height of 0.5D. In addition, when the distance between the twin channels is 0.5D, the height of the disturbed zone occurred by the digging of the new channel on the left side would be lower than the counterpart on the right. If tunnel-digging were to take place when different joints angles exist in an anaclinal slope with biased formations, the scope of the influences of the formation would differ depending on the location of the tunnel and the joint angle. The higher the average height of the ground surface where the tunnel is
located is, the broader of the scope of the influences that follow. The greater the joint angles, the broader the scope of the influence on the entire formation-changes – as well as the influences on the ground surface. The numerical simulation reveals that the simulations and testing in DDA small displacement tend to overestimate; the simulations for all other stages, however, show good results. Using a joint angle of 60° as an example, the result of the Phase2 simulation is ideal when the amount of digging is δ=2, 4mm; underestimation tends to occur when the amount of digging is at its maximum.
