摘要南嶺隧道巖溶地下水活動造成地表坍陷、洞內泥砂淤塞等病害,其原因在於隧道施工遺留的導洞長期疏排巖溶水,採用地質測繪、物探、鉆探、水文地質試驗等綜合勘察方法,查明地下水通道位置、地下水流速、流向,針對病害原因,提出攔截、封團、疏排、填充等綜合整治方案。Mine plans - drilling and cavern - part 1 : drilling
礦區平面圖.鉆探和孔洞.第1部分:鉆探The chikyu will be involved in multiple drilling and coring projects, and some of the holes it creates could be used in the future to house onsite crust monitors that would improve quake warning systems, according to cdex scientist shinichi kuramoto
根據cdex科學家倉本真一表示,地球號將會被運用於多個鉆探與巖心取樣的計畫,而其所鉆出的孔洞有些將會用來置放固定的地殼監控儀器,以加強地震預警系統。The chikyu will be involved in multiple drilling and coring projects, and some of the holes it creates could be used in the future to house on - site crust monitors that would improve quake warning systems, according to cdex scientist shinichi kuramoto

但因溶洞的分佈規律性差,現有勘探手段難於事先查明它的準確位置及大小,因而常常給施工帶來意想不到的問題:工期延長、工程量增加及工程費用增加等。本文通過現場試驗、理論計算和有限單元分析,對巖溶地區鉆孔灌注樁的施工工藝、荷載傳遞機理、持力層頂板厚度及嵌巖深度等方面進行了較為系統的研究,得出了一些重要結論,有效地指導了該類工程的設計和施工。分享友人
