摘要

藥液灌漿工法之設計，係依施工前各項調查試驗結果，考慮環境、施工及土質條件，選擇適當的灌漿材料及工法，並檢討其施工性、經濟性、工期、環境影響及改良效果等因素，以充份達成所期之灌漿目的。但是，由於土壤之複雜性、改良土體之不均勻性等因素，設計時仰賴經驗之處仍多，無法僅依力學穩定分析進行。因此，本文乃彙集國內外相關設計資料，旨在提供土木工程人員從事灌漿工法設計所需之基本概念及資料，內容包括①灌漿工法與材料之適用性；②灌漿改良範圍之決定；③灌漿量之預估；④灌漿孔之配置；⑤模擬灌漿及改良效果之檢核方式等。

The design of the chemical grouting is based on the preliminary investigation which includes the surrounding conditions and geotechnical properties. The workability during the construction, fund for the grouting, operation duration, environmental impact and appropriate grouting measures have to be taken into account to achieve the aim of grouting work. Due to the uncertain reason, such as the complication of soil properties and nonuniformity of the improvement, the conventional stability analysis could not serve as the basis for the grouting design which shall be taken the responsibility by the empirical method. So, this paper provides civil engineer with related information and fundamental concept for the grouting design which includes the follows: ①The applicability of grouting materials and methods ②The determination of the extent of grouting ③The estimating amount of the grouting ④Layout of the grouting holds ⑤The methods for grouting test and the evaluation of the grouting effect.
