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.
