Based on engineering, foundation design of super length basement under complicated karsts geological conditions is discussed, The choice of pile type is used differ from geological condition.In order to find out distributing about karsts and soil cave, it is urge to drill for each column position in the basement outside the tower in advance, 3~4 hole is demanded for each pile inside the tower, which is the reliable basis for foundation design.Accepted construction experience from the first period, the effect and method on how to deal with karsts, are summarized and improved the measures in the next period.Cost, construction convenience and safety are considered, the length of steel bar for pile, the design of pile cap and foundation slab, construction measures for prevented crack of super length basement and testing of pile foundation are expounded for reference.
