Abstract In excavation of double span tunnel，there exists a big water-eroded groove. The method of elastic foundation beam is used to cope with the situation. Acting load，calculating pattern and elastic foundation coefficient are discussed. The analytical results indicate that it is feasible to consider properly the support capacity of water-eroded groove filling. Reasonable tunnel structure and its corresponding construction method are given. The tunnel has passed though the big water-eroded groove successfully by using this method.
